  • Patent number: 6033353
    Abstract: A novel stock roll support assembly and loading method for a cushioning conversion machine that produces dunnage product from sheet stock material supplied as a roll provides for easier loading of the stock roll onto a roll support at the upstream end of the cushioning conversion machine in certain situations, such as where the machine is located against a wall or over (or under) a conveyor, etc. The stock roll support assembly is connected to a main frame of the machine for rotatably supporting a roll of sheet stock material. The stock roll support assembly includes a stock roll support mounted to the main frame for swinging movement between an operating position and a loading position. In the operating position, the stock roll support is operative to support the stock roll adjacent the main frame, and in the loading position, the stock roll support is swung away from the main frame to facilitate loading of a stock roll thereon.

    Abstract: This invention comprises apparatus and methods for folding and crimping shredded strips of sheet material into preselected lengths of interlocking, decorative material and/or bulk packaging material. The apparatus generally includes an attachment for a commercial paper shredding device which shreds sheet material therein. The apparatus comprises a movable barrier against which the shredded strips of sheet material are impelled upon being expelled from cutting blades of the shredding device. The movable barrier causes the strips to become controllably jammed within a confined area between the barrier and the cutting blades. Further insertion of additional strips into the confined area causes the strips to become compacted, folded, and crimped against a remaining dam of jammed sheet material located within the confined area. This causes the strips to fold and press against themselves, and form lengths of thin sheet material having an accordion-shaped configuration.

  • Patent number: 4755164
    Abstract: An applicator for tampons has a sleeve for the tampon and for a portion of a reciprocable pusher which can expel the tampon by causing the latter to flex outwardly a set of domed petals at the front end of the sleeve. The sleeve is formed by advancing a strip of degradable material longitudinally, by forming spaced-apart portions of the strip with transversely extending rows of hourglass-shaped webs, by converting the strip into a tubular envelope with a seam extending in parallelism with the axis of the envelope, by severing the envelope across the rows of webs so that the envelope yields a series of tubes each having a circumferentially extending set of petals (halves of webs) at each of its ends, and by cutting each tube midway between its ends to form shorter tubes (sleeves) each of which has a set of petals at one end. The petals are thereupon domed to close the respective ends of the sleeves and the other ends of the sleeves are formed with indentations which center the respective pushers.

  • Patent number: 4748838
    Abstract: A method for making a corrugated thin metal strip wherein corrugations are linear and extend obliquely from one longitudinal marginal edge to the opposite longitudinal marginal edge of the strip. The invention involves passing the thin metal strip through corrugating rolls for impressing a series of single apex, V-shaped chevron corrugations into the surface of the metal strip. The rolling of the strip between the helical gears is done in such a way that the apex of the V-shaped chevron is the last portion to leave the corrugating rolls whereby the apex is in tension and enables metal strip to be split into two obliquely corrugated metal strips along the apices of the chevron.

  • Patent number: 4497620
    Abstract: A press includes a frame, a flywheel, a motor for driving the flywheel, and a shaft. A clutch and brake assembly is provided which is actuable for engaging and disengaging the shaft to the flywheel. An eccentric is journaled upon the shaft and rotates therewith. The eccentric rotates in a block which is slidably mounted in a head to permit the block to move laterally within the head. The head is vertically movable in response to vertical movements of the block. The press also includes an upper die which is mounted on the head and a lower die which is resiliently supported upwardly on a base. Movement of the head engages and disengages the upper die and lower die. One embodiment of the press includes a second set of dies mounted to the head for cutting a continuous sheet of material into a predetermined shape.
