  • Patent number: 9028241
    Abstract: A method and apparatus are provided for automatic and hands-free threading of an elastomeric mix into a calender set of rolls comprising one or more pairs of rolls that have a nip between them. A stripper roll is positioned next to one of the rolls forming the nip and is rotated so that the outer surface of the stripper roll moves in a direction opposite to the outer surface of the adjacent roll. The stripper roll removes all or a desired portion of the elastomeric mix from the adjacent roll and causes the same to transfer to another roll. Variables such as e.g., the relative surface speed of the stripper roll, diameter of the stripper roll, and distance of the outer surface of the stripper roll from the adjacent roll can be manipulated to control the amount of the elastomeric mix that is stripped by the stripper roll.

  • Patent number: 8333582
    Abstract: A method and machine for sealing at least one cut edge of a foam board is disclosed. The foam board has a top surface, a bottom surface and at least one cut edge extending between the top surface and the bottom surface. The cut edge is passed over a heated roller to soften the edge and then passed over a second roller having a temperature that is lower than the temperature of the first roller which seals the edge. The cut edge may be milled to square the edge relative to the top and bottom of the board before the cut edge is passed over the heated roller. Additional pairs of rollers may be provided to seal the top surface and the bottom surface of the foam board.

  • Publication number: 20120292819
    Abstract: A crosslaminate is formed from two oriented plies of thermoplastic polymer material, arranged so that their orientation directions cross one another, the plies being heat sealed together. Each ply is semi-fibrillated, that is consist of linear thin regions of biaxially oriented material and thicker linear bosses between the thinner regions. The webs are sealed primarily through bonds formed at the intersection of the bosses (thicker regions). The array of bosses has a division less than 2 mm. The laminate has improved aesthetic and strength properties. A method for forming the crosslaminate involves segmental stretching of the material to form the thinner regions, and apparatus comprising intermeshing grooved stretching rollers having sharp-edged crests is described.

  • Patent number: 8231377
    Abstract: The invention provides a roll assembly including a pair of cylindrical rolls that are positioned in an opposing cooperating relation for receiving a sheet material therebetween. A plurality of projections on at least one of the rolls extending radially outward from a surface thereof and a plurality of corresponding recesses is provided on the other roll. The projections and corresponding recesses are positioned and arranged on the rolls for contacting and engaging a sheet passing between the pair of rolls. The projections each include an outermost surface portion that is positioned for contacting a discrete portion of the sheet and for entering a corresponding recess on the opposite roll. When rolls rotate about their axes, the projections engage the discrete portion of the sheet material which results in the discrete portion entering the recesses with the projections so as to stretch the sheet in multiple directions.

  • Publication number: 20120104648
    Abstract: An apparatus enables forming extruded plastic material into a strip that may be formed into an irrigation pipe. The apparatus includes a pair of juxtaposed rollers which when rotated, the linear velocity of a contact surface of one of the rollers of the pair is different from the linear velocity of a contact surface of the other roller of the pair. Thus, extruded material that passes between the rollers is concurrently stretched and flattened.

  • Patent number: 8157558
    Abstract: An apparatus and method for forming a clay slab includes a frame, a front panel supported on the frame and a rear panel supported on the frame. An outer cable is attached to the rear panel at one end and to the rear panel and to the front panel at another end. A rotatable drive axle is configured to simultaneously wind and unwind the outer cable and thereby move the front panel and the rear panel from an initial position to an intermediate position to draw a block of prepared clay into a gap defined by the front panel and the rear panel. The drive axle is further configured to simultaneously wind and unwind the outer cable in the opposite direction and thereby move the front panel and the rear panel from the intermediate position back to the initial position to remove the clay slab from the slab roller.
