  • Patent number: 4832677
    Abstract: A method and apparatus for forming draw tape bags wherein the bag material moves continuously during the manufacture, except for the last step. The apparatus may be used with an in-line system wherein a tube is extruded and a side gusset is formed to create a hem; or the apparatus may be used with an off-line system wherein folded bag material is used, and a continuous hemmer is provided to turn the loose edges. In the off-line system a constant tension dancer precedes the hemmer to maintain constant tension on the web regardless of the size of the supply roll. The web continues to move, and a cutter is actuated to move through a circle and engage the web to punch finger holes in the hem. A reel of a strip of material is continuously fed, the strip being slit longitudinally to provide the draw tapes which are inserted into the hems. A tape guide tensions the tape and assures that the tape is well within the hem, the hems are sealed, and the bags are side welded.

  • Patent number: 4688455
    Abstract: A cutting device for a belt-like object is characterized by a pair of feed rollers and another pair of feed rollers which hold from both sides an object being supplied to be cut in succession. The rollers rotate at the same speed and are mounted in a horizontal direction respectively above and below the cutting position. The rotation of a main shaft driven by a motor is transmitted to a driving shaft of the pair of feed rollers placed above the cutting position through the main driving wheel of a one-way clutch. The rotation of the main shaft is also transmitted to a driving shaft of another pair of feed rollers placed below the cutting position through a subordinate driving wheel of said one-way clutch.

  • Patent number: 4681005
    Abstract: A resaw has twin arbors with one to six blades mounted on each arbor. In addition, the resaw has a rotatable fence with a continuous belt along its periphery. Two side pressure rollers are mounted adjacent to the rotatable fence between an entrance to the resaw and the blades. A workbed of the resaw is made up of a series of spiked rollers. Just prior to an exit from the resaw, there is located a top roller which is mounted normal to the side pressure rollers and can move further away from or closer to the workbed. The arbors are each powered by an electric motor. The rotatable fence, the side pressure rollers and the spiked rollers are all powered by hydraulic motors connected to a single power source and all rotate at the same speed at any given time. The side pressure rollers are automatically adjustable so that they exert pressure towards the rotatable fence on any wood that is located between said rollers and said fence.

  • Patent number: 4619538
    Abstract: An adjustable load tear bar mechanism for a friction feed platen (15) that comprises a tear bar assembly (31) and spring loading mechanisms (33) is disclosed. The tear bar assembly (31) comprises a tear bar (51) mounted between a pair of side arms (41, 43) located on opposite ends of the platen (15). The tear bar (51) is an inverted, generally U-shaped channel. Positioned in the channel is a roller shaft (45) on which a plurality of friction feed rollers (47) are mounted. The downstream ends of the side arms (which overlie the platen) are pivotally attached to walls (11, 13) of the printer chassis. The tear bar (51) and roller shaft (45) extend between the upstream ends of the side arms (41, 43). Mounted on the roller shaft (45) so as to be rotatable therewith are arm hooks (53, 55). One of the arm hooks is part of a detent mechanism that includes teeth (125) that co-act with a spring (59) and plunger (57) housed in one of the side arms (43).

  • Patent number: 4607558
    Abstract: This machine is more particularly designed to make a series of slits across the external surface of a tire rethread band. The band is moved step-by-step by a conveyor belt; a guillotine-type blade is reciprocated up-and-down over the band supported by the conveyor belt and effects a slit in the band when the conveyor is stopped; the depth of the slits can be adjusted; the inclination of the slits with respect to the longitudinal axis of the band can be varied; the distance between the slits can be adjusted by varying the stroke of the belt advancing mechanism; the conveyor belt has an outer anti-skid surface and the tire rethread band is applied against the same by spring-biased pressure rollers which accommodate tire rethread bands of various thicknesses.

  • Patent number: 4596174
    Abstract: A high speed wire handling and cutting apparatus having particular application for efficiently providing a continuous supply of uniform dimension wire leads which are to be electrically connected (e.g. welded) to an electronic component, or the like, so that such component can be connected into an electrical circuit. The apparatus includes a wire feeding crank and an associated cross head assembly, a wire receiving crank and an associated cross head assembly, and a wire cutter disposed therebetween. The wire feeding crank and its associated cross head assembly continuously feed an accurately metered length of wire from a wire supply to the cutter, so that wire sections of precise and uniform dimension can be cut therefrom. The wire receiving crank and its associated cross head assembly embrace the sections of wire that are cut from the supply and transfer the sections from the cutter to a suitable storage facility or to the next stage in an electronic component packaging and/or manufacturing assembly line.

  • Patent number: 4432746
    Abstract: An apparatus for segmenting a continuous running web into a stream of discrete articles by cutting the web transversely at uniformly longitudinally spaced intervals; and which apparatus may also effect U-folding of each of the discrete articles. The apparatus is of the type which includes a flight of longitudinally spaced, web engaging friction plates which provide cutter access to the web through spaces intermediate adjacent friction plates. The apparatus further includes a constant clearance infeed nip which is formed in part by the spaced friction plates of the flight passing over a circumferential portion of an infeed roll having circumferentially spaced, radially extending lugs, and which lugs are configured and disposed to engage the web by extending through the spaces intermediate the spaced friction plates. Alternatively, the flight of friction plates may be integrated into a unitary apertured conveyor belt; and the cutter may be integrated into such a constant clearance nip.

    Abstract: A method and apparatus for cutting blocks of bulk material such as cheese and the like into slabs and bars wherein an elongate cutter filament is supported by and between supply and take-up spools so as to extend transversely of a slab cutting station adapted to receive a block of bulk material therein. The supply and take-up spools are operable to move the cutter filament through the block to sequentially cut slabs therefrom and to incrementally advance the cutter filament after each cut so as to remove any given segment of the cutter filament from the effective cutting length before it fatigues to possible failure. After cutting slabs from the block, the slabs are passed through a bar cutter die operative to cut the slab into a plurality of bars of substantially uniform size and weight.
