Abstract: Pre-stretched films may be used to increase the rate at which loads can be wrapped and to minimize the exertion required when using traditional handheld film. However, the edges of pre-stretched films are easily damaged, which may result in tearing or failure of the film during use. The present disclosure describes devices, systems, and methods for folding the edges of the film, resulting in a film that is less susceptible to damage and easier to use.

Abstract: An adhesive tape cutter provided with a double-portion forming means that folds a longitudinal side edge of a predetermined width of adhesive tape in the direction that its adhesive face is facing to form a double portion as a non-adhesive portion by pulling out the adhesive tape through between adhesive face-side members disposed on the side faced by the adhesive face and non-adhesive face-side members disposed on the side faced by a non-adhesive face thereof with both the members contacting and pressing against the adhesive tape.

Abstract: An assembly to crease a paper set in a booklet maker is provided. A booklet is formed in a booklet marker when a crease blade strikes the middle of the stack and pushes it toward a set of nipped crease rolls. The assembly engages spring-loaded idlers against the crease rolls after the crease blade initiates the buckle of the stack and prior to creasing. The spring loaded idlers apply a drive force to the stack that assists the formation of the crease. With the assistance of this extra drive force, the crease blade tip can be stopped in time to avoid jamming while reducing the chance of getting a cover, or more sheets tearing off the booklet. This design is compact in size and therefore may also be retrofitted into existing designs.

Abstract: A pair of facing die sections, preferably constructed of machinable plastic, are biased toward one another and their central regions are spaced to form a shallow gap. Each die section is provided with a tapered folding chamber whose wide end is open at the upstream end of the die section. Each chamber communicates with the gap by means of a shallow slot that extends longitudinally, or in the direction of travel of a tape that is drawn through the gap. The edges of the tape enter the folding chambers as the central main section of the tape enters the upstream end of the gap. While the tape edges are in the chamber they are curled and directed through the slots into the gap. By the time the edges leave the chambers these edges are folded to lie flat against opposite sides of the main section of tape. Means are provided for adjusting the die sections to operate on different widths of tape and to produce desired widths for the folded edges.

Abstract: Apparatus and methods of operation for automatically folding obstetrical pads into a so-called three-fold configuration which occupies approximately 40% less volume than two-fold pads of the prior art. The obstetrical pads, as fabricated, have two opposed, elongated tab portions extending beyond the pad proper, and the pad is folded by the apparatus so that these tab portions are juxtaposed adjacent one another in order to facilitate removal of the pad from its package and provide enhanced convenience in preparation of the pad for use. More importantly, the placement of the tab portions in this fashion permits the handling of the pad without contaminating the sterile field in the inner fold area of the pad. By virtue of the reduced volume of the three-fold pad, substantial savings are realized in the manufacturing process, in the storage facilities required for warehousing and inventory at each step in the distribution process, as well as in shipping.

A method of and apparatus for manufacturing the bags with the tabs from bag tubes wherein the tubes are continuously fed forward, one after another, tabs are applied to the tubes as the tubes travel forward and folded to overlie the other wall before the pinch closure flap is folded over. Each tab is inserted between the walls of a tube by bringing the tab into a position overlapping the one wall and separating the one wall from the other to the point where the end of the tab slips off the one wall and becomes disposed between the walls.

Abstract: Apparatus is provided for automatically effecting a widthwise folding of a long, flexible web advanced therethrough. The web is trained about a first roller at a point where the folding begins and about a second roller at a point where the folding ends. A displacement edge or bar is mounted in a fixed location equidistant from the first and second rollers, and a portion of the web is trained about the displacement edge or bar during the folding. Webs of different widths are accommodated by adjusting the positions of the first and second rollers without changing the shapes of three similar triangles. The first triangle is defined by a first point where a first edge of the web intersects the first roller, a second point where the same edge of the web intersects the second roller, and a third point where the opposite edge of the web intersects the first roller.
