Abstract: A paper feeding mechanism for selectively advancing paper a predetermined distance past a printing station of an electronic business machine. The paper feeding mechanism is adapted to utilize a supply of fan folded paper, e.g., housed in a disposable cartridge, which may be readily inserted within the paper feeding mechanism to place the electronic business machine in readiness for operation. During the printing cycle, a contact mechanism maintains a portion of the paper in contact with the printing station of the electronic business machine. After the printing occurs, an actuation mechanism is energized to move the contact mechanism away from the printing station to free the paper for advancement. At the same time, the actuation mechanism moves an advancement mechanism to advance the paper a predetermined distance past the printing station of the electronic business machine.

Abstract: The feeding mechanism serves to intermittently feed stock to a processing machine and comprises a rocker lever having at its outer end a gear segment, a crank drive comprising a crank which is operatively connected to said rocker lever, said crank drive being operable to impart an oscillation to said rocker lever, a feeding clamp comprising first and second, reversibly rotatable, toothed feed rollers arranged to mesh with each other when said feeding clamp is closed, said first feed roller being in mesh with said gear segment, a retaining clamp for holding said stock in position, and a cam operated control linkage for cyclically opening and closing said feeding clamp and retaining clamp in alternation.
Abstract: A roll feeder device for press works utilizing a barrel cam drive system having a sinusoidally grooved portion engageable with rollers secured to an indexing plate which transmits the rotational motion of the main drive shaft of the press to the feed rolls so as to coordinate feeding of material to movement of the press in such a manner that the material is fed with a substantially constant velocity during the material feed portion of the cycle. A braking system is provided in which the driven feed roll is moved away from the material being fed, in response to a camming action of a lever mechanism coordinated to the movement of the press through rotation of the main drive shaft.
Abstract: In the strip feeding apparatus of the invention, the strip material passes between a lower driven roll and an upper idler roll which is mounted on a vertically slidable adjusting plate so as to move in a pivotal manner towards and from the lower driven roll. The idler roll is mounted on the adjusting plate by means of a pivotal bracket, whereby the idler roll and its bracket can be adjusted bodily in a vertical direction to and from the lower driven roll without disturbing the action of the pressure means forcing the idler roll towards the driven roll and without disturbing the action or timing of the actuating cam which periodically produces a lifting of the idler roll against the pressure of the pressure means.
Abstract: A yarn transport mechanism for a needle band weaving machine comprising a carrier which can be placed into revolving motion with variable speed, said carrier possessing a friction coating against which there can be placed the yarn which is to be conveyed for the purpose of entrainment thereof.
Abstract: An apparatus for scanning a magnetic video tape includes a drum and a rotatable magnetic head. A freely rotatable roller and a loosening mechanism are positioned on opposite sides of the tape. When the tape stops, the loosening mechanism is driven toward the roller and thus engages the tape between the loosening mechanism and the roller. Rotation of the loosening mechanism then loosens the tape.
