Abstract: A registration device for use in silk screen printing of garments and other articles. The device facilitates the accurate positioning of the garment or other article to be printed. The device has a support arm which is held in a fixed position in respect to the platen of the silk screen printing apparatus. The support arm holds a frame which is affixable to a transparent sheet. The sheet is taped to the platen and marked with the silk screen indicia. The frame is then moved over the transparent sheet and taped to the sheet. The sheet is then detached from the platen and moved away therefrom on the frame. The garment to be marked is then placed on the platen, and the transparent sheet and frame is temporarily returned to its original position and placed over the garment to be marked. The garment is then alignd so that the spot on the garment to be marked is directly below the indicia on the transparent sheet. The frame and sheet are then moved away and the garment is accurately printed.

Abstract: A typewriter carriage cable snubber which is automatically reset at the time power is turned on is described. The cable is normally tensioned by a mechanism which is spring driven to maintain the cable tension at the proper value, and a snubber is provided to prevent the positioner from allowing the cable path to shorten under the increased tension that occurs during carriage acceleration. When the power is turned off, the cable tends to shrink due to the decreased temperature. When power is turned on, the carriage is initialized by positioning it at the left end of its range. At this position the cable tensioning mechanism can be reset to allow a shorter cable length by having an extension of the carriage disengage the snubber, allowing the positioning mechanism to reset itself to a shorter cable length.

Abstract: A stream of shingled printed products coming off a press at high speed, with variable speed of conveyance and with variable shingle spacing, has alternate products divided into two streams conveyed at reduced speed. Thus two cyclically driven chains present alternating gripper links at a pickup station to grip and transport the alternate products along diverging paths for release on a corresponding pair of conveyor lines for the divided product streams. To conform with varying speeds and spacings, the gripper chain drive is synchronized to operate the grippers as each individual product arrives.

Abstract: Intermediate or end products comprising a plurality of interstuffed and overlapping folded printed signatures or sheets are straddlingly fed or conveyed by a plurality of collating conveyors of a circulatingly driven collating cylinder or drum to a product transfer location or pick-up region. At the product pick-up region the intermediate or end products are picked-up or taken-over by a product withdrawal conveyor or device. The product withdrawal conveyor comprises holding or gripping mechanisms which are mounted in spaced relationship on a traction member. These holding mechanisms comprise pivotable clamping mechanisms which are laterally pivotable into a location between the halves or portions of the folded products. These halves or portions are raised or separated from each other. These clamping mechanisms press and thus clamp the intermediate or end products against a counter-element.
