    摘要： Method of and device for making perforations in the inner gusset portions of a tubular web of plastics foil which is provided with side gussets. Such perforations serve to remove air from the interior of bags to be manufactured from the tubular web. According to the invention the gussets are opened over a distance sufficient to introduce, in the interior thereof, a punching member, which is activated by exerting a pressure from outside the tubular web. A device adapted to perform this method comprises a separate carrier provided at either one of its ends with rolls and adapted to be introduced into the interior of the tubular web where it is supported and maintained in its place lengthwise of the web, by two sets of rolls which are situated at the exterior of the tubular web. The carrier is provided with perforating units and the machine frame outside the tubular foil is provided with means to exert through the web material, a force and to activate the perforating units. Preferably elements for opening the tubular foil comprise sets of conical discs which are rotatable about spindles, such that one each in every set of rolls is situated in each of the two gusset halves.

    摘要： A punching device comprising a pair of opposed complementary dies vertically guided by a pair of guide rods each rotatably connected to a crank pin to continuously punch band material moving between the dies. The crank pins rotate synchronously in opposed directions with their crank centers spaced only vertically relative to the working plane. Each of the dies supports a plurality of cooperating tools and the tools in one of the dies are independently axially movable male punches sealingly guided in ducts communicating with a closed chamber filled with a fluid.

    摘要： In a process and apparatus for cutting portions such as labels or tickets from a continuously moving web, the web is passed between a blade and a co-operating support member. As the web moves past the blade, the blade is displaced during the cutting operation in the same direction as the web and synchronously therewith, but over a shorter distance than the length of the portion to be cut out. The blade is then disengaged from the web and returned to its initial starting position. The support member may also be displaced in the opposite direction to the movement of the web and blade during the cutting operation.

    摘要： A machine for punching a series of aligned holes in suitable stock, e.g., for forming binding holes in a stack of sheet material such as paper. The machine is electrically operated and generally includes a pressure bar which is guidingly constrained for movement along a vertical plane. A plurality of punches and coating dies are included and are arranged in a row and suitably attached to base structure directly beneath the pressure bar. Downward movement of the pressure bar is effective to drive the lower portions of selected ones of the punches into the respective dies and upward movement of the pressure bar is effective to return those driven punches, thus constituting one cycle thereof. A pair of lever arms are provided, having one of the ends thereof coupled to the pressure bar and being pivotally attached to the base and are suitably power driven by structure including a clutch which is operably coupled to the other ends of the lever arms for causing reciprocating movement thereof. Also included is switching structure for selectively causing the clutch to be engaged to drive the punches through the described cycle.
