Abstract: The invention concerns a clip conveyor apparatus for conveying a clip line (2) comprising a plurality of clips in a clipping machine, in particular a sausage clipping machine, comprising a drive unit (10) and an advance element (20) which is coupled with its drive end (22) to the drive unit (10) and is drivable by the drive unit (10) in such a way that its conveyor end (24) describes an elliptical path and for stepwise conveyance of the clip line (2) engages into intermediate spaces between two clips of the clip line (2) and conveys same stepwise in the advance direction (V), wherein there is provided an adjusting device (30) having a pivot axis (36) about which the transport element (20) is pivotable and which is adjustable in its position without a tool in such a way that at least one of the axes of the elliptical path described by the conveyor end (24) is variable.

Abstract: This invention relates to an improved strip label printer and especially to a shuttle mechanism therefor that advances the label strip in incremental fashion and, in addition, functions to actuate the printing head during the time the shuttle is returning to its original position preparatory to starting another label-advancing stroke. This shuttle mechanism is characterized by a specially-shaped slide block that includes label-engaging ears working through slots in a bedplate over which the label strip moves and also a hump-like fulcrum between these ears that engages the underside of the bedplate and functions to tilt the slide block in a direction as to elevate the ears into operative position during the forward stroke lowering them into inoperative position beneath the strip on the return stroke when shuttled back and forth by the crank and pitman drive therefor.

Abstract: A single rotary cam has one cam track which controls movement of the transport claw in both the forward and reverse film-transport directions. The cam track is so configured that the claw motion constituting the one-frame advancement motion for forward transport constitutes part of the return stroke during reverse transport, and vice versa. The cam-track configuration is such that, despite the constancy of the motion performed by the claw, the position of projected frames is unchanged when switching over between forward- and reverse-transport modes of operation.
