Abstract: In the field of transport paths used typically in postage meters, it is sometimes desired to prevent withdrawal of items in the opposite direction to forward travel along the transport path. The disclosure relates to a one way gate (10) for such a transport path including a transport surface (11). The gate includes a rotatable roller (17) disposed opposite the surface such that an item traveling forwardly along the transport path engages and rotates the roller (17); and a device preventing rotation of the roller (17) in a direction corresponding to withdrawal of an item (22) in a reverse direction along the transport path.

Abstract: A web engagement system for an off-reel printing press comprising a guide piece, a guide channel and drive stations for the displacement of the guide piece. The guide channel accommodates and guides the guide piece and is located on the frame of the press between the drive stations. The guide piece is slightly longer than the distance separating the various drive stations. The advance of the guide piece is caused as a result of the displacement of a slide equipped with wedging rollers which alternately grip and release the guide piece. A pair of wedging rollers prevents the return movement of the guide piece. The invention is used for introducing paper webs unwinding continuously in an off-reel printing press.

Abstract: A pair of arms is hingedly connected to a rocker. These arms support the pressing bar. At their opposite ends the arms are pivotably mounted such to the casing of the appratus that in one position thereof the axis of rotation of the lower feeding roller coincides with the pivot axis of the pivotal point of the arms at the casing. By this design it is no longer necessary to adjust the apparatus for the intermittent feeding of a web-shaped workpiece by utilizing auxiliary structures to various respective thicknesses of the web being fed.

Abstract: A top cover is peeled from a component supply tape by passing the cover around a guide surface and in a peeling direction generally reverse to the feeding direction of the supply tape while moving the guide surface in the peeling direction in order to minimize the tension necessary to accomplish the peeling.

Abstract: A multifunctional cassette (1) for a printer (131), in which the cassette (1) that can be arranged in the printer (131) is provided with first, second and third chambers (31, 35, 37). The second chamber (35) and the first chamber (31) can accommodate a supply reel (59) and a takeup reel (57), respectively, for transport of a color transfer strip (55) past the printing head (143), while the third chamber (37) can comprise a supply of a data strip (41) to be transported along the printing head (143). Pins (103, 105) brake the web when the cassette is not in the printer. Whether using or not using the first and second chambers (31, 35), the multifunctional use of the cassette (1) becomes possible for different types of printers, such as black-and-white printers and color printers.

Abstract: A hitch feed assembly for automatically aligning individual lead frames at a bonding site in both the longitudinal and lateral directions is disclosed. The alignment is attained as a result of the cooperation between a plurality of chamfered pawls and the sprocket holes in the film-carrier. The pawls are chamfered along three sides in order to attain alignment in both the longitudinal and lateral directions. Significantly, the pawls come into operational contact with the sprocket holes while the lead frame film-carrier is under minimal tension so that the pressure exerted on the edges of the sprocket holes by the pawls will be minimal, thereby avoiding any deformation in the shape of the sprocket holes.

Abstract: A fastener feed assembly for a tool such as a power screwdriver having a drive member such as a rotatable bit includes a base fixed to the tool and a nose assembly slidably related to the base. The nose assembly includes a workpiece engaging surface, and when the tool is moved toward the workpiece during a fastener driving operation, the base moves toward the nose assembly. A return spring separates the base and nose assembly when the tool is withdrawn away from the workpiece. A strip of fasteners is fed from a magazine along a feed path through the nose assembly with sequential fasteners located in a drive position. Normally the drive member is spaced from a fastener in the drive position. During movement of the tool toward the workpiece in a driving operation, the drive member moves into engagement with a fastener in the drive position, and then continues to move in order to drive the fastener into the workpiece. A pawl is engageable with the strip in order to advance the strip along the feed path.
