    摘要： Cutter and creaser apparatus that cuts and creases sheets and thereafter strips the cutout portions from the sheet includes a drive mechanism that is capable of either intermittently stopping the sheet for the cutting and creasing operations or varying the speed of the sheet as it is conveyed through the cutter and creaser apparatus. The drive mechanism includes a drive shaft driven at constant velocity by suitable drive means. A speed control shaft is mounted in parallel spaced relation to the main drive shaft and is connected thereto by a pair of meshing gears so that the speed control shaft rotates at the same angular velocity as the drive shaft. A sun gear of a planetary gear assembly is connected to the drive shaft for rotation therewith and meshes with a planet gear that, in turn, meshes with the internal toothed portion of the ring gear. The external toothed portion of the ring gear meshes with a drive gear for the press sheet conveyor shaft on which a pair of drive sprockets are mounted in spaced relation to each other. A lever is pivotally connected to the drive shaft intermediate its end portions and has one end portion connected to the planet gear. The other end portion has a cam follower mounted thereon that is maintained in abutting relation with the cam surface of a cam secured to and rotatable with the speed control shaft. The cam upon rotation pivots the lever and moves the planet gear. The angular velocity of displacement of the planet gear through the lever determines the relative velocity of the sheet conveyor. Another embodiment includes bevel gear arrangements to selectively decrease and increase the speed of the conveyor mechanism.

    摘要： The side register mechanism is positioned between a sheet feeder mechanism and the feed rolls of the press and includes a plurality of spaced parallel endless tapes reeved around spaced pulleys mounted on a feed board. The tapes are parallel to the longitudinal axis of the press and are driven by certain of the pulleys to convey separate sheets from the feeder to the press. There are a plurality of parallel suction device guide members positioned below the upper run of the tapes and suction heads are arranged to move reciprocally in the guides. The guides are positioned at an acute angle to the tapes and the suction devices in the guides engage the sheet adjacent the leading edge and direct the sheet laterally toward a side of the feed board as the sheet is conveyed toward the press feed rolls by the tapes. The lateral movement of the sheet moves the side edge of the sheet beneath a rotating brush member that urges the sheet side edge against a moving vertical endless side guide tape. The rotating brush member urges the sheet side edge against and maintains the sheet side edge in abutting relation with the side guide tape. The sheet is thus brought into and maintained in side register and conveyed in side register to the feed rolls. Endless driven chains with stop members move at a slightly lower linear velocity than the main conveying tape so that the front edge of the sheet is maintained in abutting relation with the stops. The suction devices are arranged in pairs and are retracted as they move rearwardly toward the feeder.

    摘要： The cutter and creaser includes a sheet feeder that feeds sheets down an inclined table to a sheet transfer unit. The front and side edges of the sheet are moved into register in the transfer unit and accelerated to press speed. The front edge of the sheet is engaged by grippers on a transverse gripper bar and conveyed through the press by an endless chain conveyor device. The press unit includes a cutter and creaser section, a stripper section and a delivery section. The cutter and creaser section has a lower platen mounted on a pair of eccentric shafts that provide a non-circular oscillatory type motion for the upper horizontal surface of the lower platen. The motion imparted to the upper surface of the lower platen has both horizontal and vertical components. An upper platen is positioned in overlying relation with the lower platen and is supported for horizontal movement in the press side frames. The upper platen is connected to the lower platen so that the upper platen reciprocates horizontally with the lower platen. The sheet conveyed by the endless chain gripper mechanism is positioned between the platens as the lower platen moves upwardly into abutting relation with the upper platen so that the elements on either the upper or lower platen cut and crease the sheet between the platens. The sheet is thereafter transferred by the conveyor mechanism to a stripper section where the cutout portions are removed from the sheet by means of dies in an upper stripper platen. The lower stripper platen is also mounted on a pair of eccentric shafts and is arranged to move the upper horizontal surface in a similar non-circular oscillatory path with both horizontal and vertical components and into abutting relation with the upper platen. The upper platen is slidably supported in the press side frame members and connected to the lower platen for horizontal reciprocatory motion therewith. The grippers on the endless conveyor chains convey the sheet from the stripper section to the delivery section where the grippers open and the sheets are released and stacked on a receiver. The drive means for the various sections of the cutter and creaser includes a single motor that is drivingly connected to both of the eccentric shafts in the cutter and creaser section. Gearing and shafting connects one eccentric shaft in the cutter and creaser section with the drive mechanisms in the transfer section, the stripper section and the delivery section so that all of the components of the cutter and creaser are mechanically connected and driven in timed relation.
