摘要： A photographic printer wherein a web of photographic paper is being withdrawn by advancing rolls stepwise from a supply reel and is fed toward a copying station where successive increments of the web are exposed to light during intervals of idleness of the advancing rolls. The copying station is followed by a loop former for the web, by two normally spaced-apart rollers which are located at the opposite sides of the path for the web, and by a motor-driven flangeless takeup reel. One of the rollers is coupled to a hysteresis brake and the other roller can be propelled toward the one roller by an electromagnet which is energized when the motor for the take-up reel is arrested whereby the rollers pinch the web with a force which prevents any slippage of the web. The motor is started and stopped when the size of the loop respectively reaches a preselected maximum and a preselected minimum value. If the inertia of the take-up reel is so high that the latter continues to rotate after stoppage of the motor and after the convolutions of the web are tightly packed thereon, the web rotates the rollers against the opposition of the brake which is adjustable to insure that the rollers begin to rotate before the web breaks. The brake brings about a controlled deceleration of the web and takeup reel to zero speed.

摘要： A copying machine admits a web of freshly exposed photographic paper directly into a cassette whose core engages and convolutes the web therearound. The progress of engagement between the leader of the web and the core is monitored by comparing the peripheral speed of the core with the peripheral speed of a rotor forming part of an advancing roll for the web and receiving torque from a variable-speed motor which also drives the core. The peripheral speed of the rotor increases when the leader of the web is adequately attached to the core, and this is detected by a circuit having first and second photoelectronic monitoring devices which respectively monitor the peripheral speeds of the rotor and the core. The signals which are generated by the monitoring devices are processed, and the processed signals are used to change the speed of the variable-speed motor, to deactivate a catcher mechanism which directs the leader of the web toward the core and assists in the establishment of adequate engagement between the leader and the core, to change the supply of energy to the motor as the diameter of convoluted web on the core increases, and/or to actuate an alarm device when the completion of attachment of the leader to the core is unduly delayed.

摘要： A one-piece clip of flexible metallic plastic material has a first section which can be separably affixed to a belt conveyor, and an elongated slotted second section. A web of photosensitive material is caused to extend through the slot of the second section so that its leader is located at one side and the next-following portion of the web is located at the other side of the slot. The leader is then folded against the respective major surface of the second section, and the web is form-lockingly connected to the second section. The form-locking connection can be established by one or more pairs of complementary tooth-shaped protuberances which extend into the slot and penetrate into and through the folded portion of the web behind the leader, by securing the leader to the next-following portion of the web by a clamp in an enlarged window-like portion of the slot, or by bonding a small part of the leader to the next-following portion of the web in such window-like portion of the slot.

摘要： A photographic copying machine wherein each of the three color filters comprises several triangular sectors which are pivotable about parallel axes into and from the path of copying light between first positions outside of the path, second positions of full overlap with the path and a finite or infinite number of intermediate positions. The pulleys for the sectors of each filter are rotatable by a discrete endless cord or cable which is further trained over a wheel receiving torque from a crank drive designed to move the sectors into the path of the light beam through progressively greater angles during movement from the second toward the first positions and through progressively smaller angles during movement from the first to the second positions under the action of a reversible stepping motor so that the crank drive can compensate for the lack of linearity between the filtering action of the sectors and the extent to which they project into the path of copying light. A device is provided to limit the extent of movement of sectors from the first toward the second positions so as to ensure that the movement of the sectors is terminated when the respective filter extends across a selected portion of the path for the light beam. A step-down gearing is interposed between the stepping motor and the crank drive.

摘要： Apparatus for winding webs of photographic film like onto the hub of a reel in a cassette has a flexible band one end of which is secured to the hub and the other end of which is connected to a coupling unit having a normally closed clamping mechanism for the leader of a web. The leader can be threaded through an inlet opening of the cassette and into the coupling unit when the clamping mechanism is held in open position by a permanent magnet which is installed in the cassette adjacent to the opening. When the hub is rotated in a direction to convolute the band and thereupon the web therearound, the coupling unit is withdrawn from the field to the permanent magnet and is confined in a peripheral recess of the reel. If the web is thereupon unwound, the coupling unit is withdrawn from the recess and is advanced toward the opening so that the magnet opens the clamping mechanism and the latter permits withdrawal of the leader of the web therefrom. The clamping mechanism thereupon remains open until an operator inserts the leader of a fresh web and causes the hub to rotate in a direction to collect the band.

摘要： Successive exposed photographic films are connected, either individually or in groups of two or more, to discrete sheet-like leaders which are transported along an elongated first path extending through the baths and the dryer of a developing unit. The leaders are separated from the respective webs downstream of the developing unit but upstream of a copying unit for developed films, and the separated leaders are directed into a second path to be gathered in a receptacle. The separation involves severing the leading end of each web close behind the respective leader, and the thus separated webs are caused to continue to advance along the first path through a magazine and thence into the copying unit. The severing mechanism includes a stationary first knife and a second knife which is movable relative to the first knife between a first position in which an oncoming leader is free to enter the second path and a second position in which the knives cooperate to sever the leading end of the web behind the leader in the second path.

摘要： Apparatus for convoluting exposed and copied photographic films on the cores of takeup reels has an advancing mechanism which transports successive films along a given path so that the leaders of successive films can be engaged by the gripper of a pivotable arm serving to transfer the leader of the film in the path toward the peripheral surface of the core of an empty takeup reel. The reel has no flanges or is provided with a single flange carrying or adjacent a fixedly mounted or movable protuberance which defines with the peripheral surface of the core a gap for the leader of the film. Once the leader has entered the gap and the takeup reel is set in rotary motion, the film is wound onto the protuberance and is thus affixed to the core. The length of the protuberance is less than the axial length of the core but exceeds one-fourth of such axial length.

摘要： A photographic copying machine wherein the images of successive frames on a long roll of spliced-together exposed and developed customer films are copied while successive films are advanced stepwise from a supply reel on a first driven mandrel toward and is convoluted on a takeup reel on a second driven mandrel. The copying machine employs a third mandrel which can support a fresh roll in the plane of the roll on the first mandrel, and a fourth mandrel which can support an empty takeup reel in the plane of the rotating takeup reel. The leader of the fresh roll is located adjacent the film path ahead of the copying station and is automatically advanced into the range of an automatic attaching mechanism when the trailing end of the expiring roll has advanced beyond the copying station. The attaching mechanism secures the leader of the fresh roll to the core of the empty takeup reel, and the machine is then ready to make copies of frames forming part of the fresh roll. The filled takeup reel on the second mandrel is replaced with an empty takeup reel and a fresh roll is placed onto the first mandrel while the machine copies the frames of the roll which is supported by the third mandrel and is convoluted on the takeup reel on the fourth mandrel.

摘要： Apparatus for classifying photographic prints which are severed from the leader of a downwardly moving web of exposed and developed photographic paper has side walls which define a downwardly extending channel whose upper end constitutes an inlet for descending prints and whose lower end has two or more discrete outlets. The channel contains one or more blade-like switching members which are movable between several positions to thereby establish paths for descent of sheets from the inlet into a selected outlet. The switching member or members are movable between such positions by electromagnets which are installed externally of the channel and each of which can attract or release one or more swtiching members. The channel can be mounted on a pivotable carrier which can move at least one outlet between two different positions for admission of prints which descend through such outlet into either of two discrete receptacles.
