Abstract: A bulk material feeder (10) has two rollers (12,14), at least the lower (14) of which is driven (24,26). Strip material (34) is threaded around the side of the upper roller (12) toward the direction of feed, between the rollers (12,14), around the side of the lower roller (14) opposite the direction of feed and to downstream machinery (38) spaced from the feeder (10). Roller (12,14) spacing is greater than material (34) thickness precluding compression of the material (34). Feed is produced by friction between the roller (14) and material (34) only. Feed rate is greater than usage thereby producing a depending loop (40) between the feeder (10) and the downstream machinery (38). In one embodiment, increasing loop (40) size decreases material (34) and roller (14) contact, causing relative slippage and a discontinuance of feed. In another embodiment, both rollers (12,14) are driven and loop (40) size is limited by a photoelectric device (42) and associated control circuitry.

Abstract: An apparatus for feeding fabric in a tensionless and distortion free manner to a fabric treating device. The fabric feeding apparatus comprises a loop forming station, a feeding station and an operator-collector station. The loop forming station continuously forms a tensionless loop of fabric by a pair of driven puller rolls, caused to activate by a signal from a photoelectric combination. The loop of fabric is sequentially fed to a feeding station by the controlled movement of a pin clamping assembly. The movement of the pin clamping assembly causes the photoelectric combination to send a signal activating the puller rolls to reform a tensionless loop. This sequence of pin clamping assembly movement and loop formation causes fabric to be continuously fed in a tensionless and distortion free manner to a fabric treating device.

Abstract: A rolling loop camera has a rotor which is arranged to clamp successive frames of the film against the surface of a fiber optic device. The rotor comprises a number of clamping devices with gaps between them, which devices roll over the film on the said surface. The gaps between the clamping devices receive the film which has been formed into a loop by supply means and the movement of the rotor causes the loop to roll across the said surface, thus placing the next frame on the surface for exposure. The film between the supply means and the loop is essentially supported by only the resilience of the film, and thus sliding of the film along a stationary surface while the loop is being formed is avoided. Each clamping device comprises a group of rollers and may include a belt supported by the rollers. As the rotor is operated, the clamping devices move around an endless path which in one embodiment is circular and in another embodiment is oval.

The shuttle means are synchronized with the tool means so that the work station web velocity at the time the tool means contact the web is substantially equal to the tangential velocity of the tool means.

Abstract: A fresh web of cigarette paper or the like is spliced to the running web by a uniting band, which is adhesive at both sides, after the fresh web is accelerated to the speed of the running web. The uniting band is placed between the running web and the leader of the fresh web, and the running web is shifted sideways to adhere to the adjacent side of the uniting band as well as to move the other side of the uniting band against the fresh web as soon as the speed of the fresh web rises to that of the running web.
