Abstract: In order to prepare stained glass chips so that they can be assembled together into a stained glass window or other work, the edges of the chips are wrapped with foil. This foil is dispensed from a roll along a path to a wrapping roller. The roller has a groove with a step and defines portions of different widths to accommodate stained glass chips and foil of different widths. The size of the groove portions are wider than the chips so that the foil will wrap around the edges of the chip and be pushed into contact with the side of the chip lying adjacent to its edges when the chip is pressed against the groove portions. Rotation of the chip also rotates the wrapping roller which is mounted so as to be free to rotate. This pulls the foil being applied to the chip.

Abstract: In a machine for sealing forwardly traveling cartons with adhering tape lapping folded stacked flaps as top and/or bottom closure means to prevent normally projecting tape applicator means from applying to such closure means of each carton excessive inward pressure which may cause such deflection thereof as to catch into and break back out an edge portion of the carton back end wall. Movable mounted tape applicator means is projectable into a defined path of forward travel of a folded stacked flap closure of an advancing carton for depression by the latter as it travels forwad thereover for application of tape to such forwadly traveling closure. Mechanism that is alternately projectable and depressible of the tape applicator means is located initially in the path of forward travel of each such carton for depressive manipulation of this projecting applicator means upon contact by the advancing carton.

Abstract: A box-sealing machine in which prismatic boxes to be sealed by a sticking tape are caused to advance on a conveying horizontal path to arrive beneath a sealing head which applies a sticker to the two folded down top flaps of the box to seal the latter, the sealing head dropping onto the box wall to effect sealing and being lifted as sealing is completed, to repeat the operation for each box being presented to the sealing head in succession, the improvement consisting in that a cutoff valve is provided in the fluid-operated circuit which lifts and depresses the sealing head so as to stop the descending movement of the sealing head on the box when a preselected pressure is attained in said fluid-operated control circuitry. The boxes are not damaged by the weight of the sealing head insisting thereon during progress of the sealing operation proper, and exceedingly long up and down strokes of the sealing head are avoided when comparatively tall boxes are to be sealed.

Abstract: A parallelogram linkage controls the speed of a sealing and cutting bar while in engagement with a polyethylene wrap while the wrap is being sealed around an object moving along a conveyor. The linkage assures synchronism between the speeds of the sealing and cutting bar and a resilient roller between which the wrap is pressed during sealing and cutting. Pressure on the sealing and cutting bar is controlled by an adjustable but controllable air pressure link. Sealable wrap is uniquely stored on the top and bottom sides of the conveyor such that it may be freely released when the object engages a web formed by the initial sealing of the two wraps together at a wrapping station. Once the wraps have been cut and sealed to form a new web at the rear of the previously wrapped object, the web is drawn back to position it for engagement by the next object in the path.

Abstract: A device for applying lengths of a heat sealable film over the open ends of cups. The device includes means which engage the end of a supply length of the film which is coiled in a cartridge, pull a predetermined length of the film from the cartridge, move the cup and predetermined length of film into engagement, heat fuse the film to the lip of the cup, and cut the fused length of film from the supply length at the cartridge.

Abstract: A pack of paper money is inserted into a binding apparatus and positioned within multiple loops of a tape in involuted state, whereupon clampers grasp the pack from opposites thereof, an extension on one clamper pressing and holding the inner leading end of the tape against the pack, and a roller device draws a trailing part of the tape to tighten the tape loops around the pack. A cutter cuts the tape at the trailing part to form an outer trailing extremity of the tape, which is stuck with adhesive to the tightened tape thereby to complete the binding of the pack. The moving parts of the apparatus are controlled and actuated automatically when the pack is inserted into binding position in the apparatus.

Abstract: A tape dispenser for use in winding tape about a rotating body generally includes a frame mounted on a base with adhesive tape mounted on a reel on the frame. The tape is run from the reel to a holding means which in the preferred form is a vacuum surface which holds the tape thereon but permits it to slide along the surface. The tape is fed in a manner in which the adhesive side faces outward from the vacuum surface. The dispenser has displacement means which pivots the frame and moves it toward the rotating body until the body touches the adhesive of the tape at or near the vacuum surface. The rotation of the rotating body causes tape to be payed from the reel until a predetermined length of tape is wound around the body. Thereafter, it is cut between the body and the vacuum surface.
