A continuous multi-layer film includes a support layer having a first film surface, and a hard coat layer, formed on the support layer, having a second film surface, and having a curling tendency in an inward direction. In the decurling method, the multi-layer film is transported. A first transition of the support layer in the multi-layer film being transported into a rubber phase is induced by supplying fluid vapor on the support layer. After supplying the fluid vapor, a second transition of the support layer from the rubber phase into a glass phase is induced. The multi-layer film is transported while a portion of the support layer in the rubber phase is prevented from contacting a solid object. The hard coat layer is formed from a polymer produced from an ultraviolet curable compound, and the support layer is formed from cellulose acylate.

A carrying apparatus carries a battery electrode member (an electrode material film web or an electrode film). The carrying apparatus includes a carrier for holding while curving, and then carrying the electrode member. The carrier is configured to hold the electrode member at a position that doesn't cause a contact with components for another process at a downstream along a carrying direction. Since the electrode member is curved, its stiffness along the carrying direction is strengthened and thereby sagging down is prevented. In addition, the holding position by the carrier is the position that doesn't cause a contact with components for another process at a downstream along a carrying direction. Therefore, according to the carrying apparatus, it is possible to carry the electrode member (an end of an electrode material web or an electrode) to a target position reliably.

The present invention relates to a packaging machine which has transport means in the form of two transport chains (5, 6) for lateral grasping and transporting of a length of material (7) consisting of packaging material. In particular with longer plants above approximately 10 meters in transport length the stretching property of the transport chains owing to the load has a marked effect on the precision of the transport distance. This results in fluctuations of the transport distance between the two transport chains and therefore distortions of the length of material, which, depending on the type of packaging material, can even lead to tearing of the length of material. In order to minimize these fluctuations, the first transport means (5) has a first engagement element (10) engaging in the first transport means (5) and the second transport means (6) a second engagement element (11) engaging in the second transport means (6), the first engagement element (10) being coupled to the second engagement element (11) in such a way that the two engagement elements are synchronized.

A draw-in device for feeding a plurality of printing stock webs, preferably paper webs, in which draw-in elements of finite length grasp the start of a paper web and draw it out of reel changers and draw mechanisms through printing units and up to folding units. An electronic memory is provided in which are stored the lengths of all possible feed paths in the printing machine and the draw-in elements can be switched on at different times corresponding to the different lengths of the feed paths and the resulting time differences at a given feed rate via an electronic computer connected with the memory and can be switched off simultaneously. It is also possible to refeed a web of printing stock which was torn during the print process so as to substantially reduce wasted paper.

Tenter for an endless fabric, especially for use by heat treatment as a part process in connection with manufacturing of fabric for a paper machine comprising several carriages (1) for guiding the rims of the fabric material by means of a carrier (2) for each carriage (1) which is connected with a drive chain. Each carriage (1) comprises at least one spring (4) arranged between the carrier (2) and an abutment in the carriage (1) such that the velocity of each carriage (1) substantially corresponds with the speed of the fabric rim. It also includes a mechanism for registering and monitoring the tension force in the material based on which the velocity of the drive chain and the carrier (2) is adjusted to maintain a desired velocity for the fabric through the heat treatment zone.

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.

Conventional clips must be manufactured with high precision and run the risk of becoming stiff in the course of time or even to become inoperative in extreme cases due to sediments in their pivoting mechanism. In order to obtain a clip which remains operational in spite of sediments and the danger of clogging and which is furthermore easy to assemble and disassemble, the clip lever is supported with a first bearing part on another bearing part on the side of the clip body, forming a kind of rocking bearing. The rocking bearing can in particular be composed of a knife-edge or rolling bearing. This clip is particularly useful for plastics stretching machines.

A traveling web transport assembly for transporting a web of textile material includes an endless chain having a plurality of web engaging members which engage one edge portion of the textile material web. The endless chain is formed with a plurality of cylindrical hub members each receiving a pin member therethrough. Each pin member is connected to an adjacent pin member by a pin link component and each hub member is connected to an adjacent hub member by a hub link component, the pin link components and the hub link components being arranged in alternating manner. A guide roller assembly mounted on each hub member includes an outer roller element rotatably supported on a ball bearing assembly. A lubrication conduit component includes a throughbore formed in a selected one of the hub and pin link components associated with each respective hub member and opening into the ball bearing assembly for introducing lubricant to the ball bearing assembly.

A photographic developing apparatus has an elastic conveyor belt and at least one clamp which is designed to be mounted on the conveyor belt and to engage a strip of photographic material. The clamp has spaced gripping elements which define an opening of width less than that of the conveyor belt and are arranged to engage the marginal portions of the belt. A mechanism for mounting the clamp on the conveyor belt is also provided and includes a female die as well as a male die. The mounting mechanism additionally includes means for juxtaposing the clamp and the belt with one another in such a manner that the central portion of the belt and the opening in the clamp are each in register with a cavity in the female die while the marginal portions of the belt are movably confined between the clamp and support surfaces on the female die. When the clamp and the belt are thus positioned, the male die is moved into the female die. This causes the marginal portions of the belt to approach one another. When the marginal portions are released from their confinement, they snap into the opening of the clamp. The male die is then withdrawn so that the conveyor belt straightens and the marginal portions thereof come into firm engagement with the gripping elements of the clamp.

A feeding means for feeding a material web in a packaging machine comprises feeding chains, sprocket wheels and an engagement element for feeding the feeding chains. In order to facilitate the insertion and clamping of the material web the engagement member is designed such that in a first portion of the travelling section the movable clamping member is lifted from the fixed clamping member in a substantially vertical direction and in a second portion of the travelling section following the first portion the movable clamping member is additionally moved laterally away from the edge of the material web to be gripped.
