Abstract: A continuous paper web-moving mechanism has a supply roll on which the paper is wound and pulled from the supply roll by a drive roll that engages the paper on its surface by a pressure exerted against the paper at that point. In this preferred embodiment the pressure is exerted by a thermal printhead resiliently mounted to force the paper against the drive roll. A leaf spring is mounted at one end of the drive roll, bearing against the edge of the wound paper, providing a friction drag on the drive roll. Also, the drive roll is kept in a fixed lateral position by the force of the leaf spring, aiding in aligning the paper. The tension between the supply roll and the drive roll is such that the paper is stiffened, providing a contact with the surface of the drive roller in a tangential line.

Abstract: A feeder device is described that causes two or more strips of unvulcanized rubber composition to be fed simultaneously at substantially the same linear rate. The feeder device includes a pair of opposed feed rolls between which the rubber strips are drawn mounted to rotate freely about their respective axis. During operation of the feeder device the feed rolls are urged toward one another but not with sufficient force to cause cutting through of the rubber strips. The rate at which the strips simultaneously advance through the feeder device is determined by the speed at which feed rolls rotate which, in turn, is dependent upon the rate at which at least one of the rubber strips is being advanced.

Abstract: In apparatus for pouch forming, filling and sealing, a printed web, having registration marks at locations where transverse seals are to be formed in order to form a pouch, is fed through drive rolls; over a plow which forms a longitudinal fold in the web; around a sealing wheel having lands which the web contacts to form transverse pouch-forming seals; around a filler where product is poured into the pouches; past a top sealer and a cutoff where the pouch forming is completed and the individual pouches are severed by knives. A photoelectric scanner scans the registration marks and produces a pulse when each passes the scanner. An electric eye cooperating with a disk driven by the machine determines the position of the sealer lands. A tachometer driven by the machine produces pulses proportional to the speed of the machine. A stepping motor continuously drives the drive rolls.

Abstract: A special blending vessel lends itself to shifting from one continuously blended product to the next in a continuous flow with a sharp change so that there is substantially no mixing of the two products at the change over. There are two sets of ingredient inputs and product outputs for the blending vessel. And, there is a follower type divider that separates one set of ingredient inputs and product output from the other set. When a shift is to be made from the one product to the next, the ingredients of the second product are introduced and blended in the vessel while displacing the remainder of the one product without mixing therewith. Then the outputs are switched so that the second product follows with an abrupt change from the first product to the second.
