Abstract: A product, apparatus and process for lamination of a sheet of polymer film onto a sheet of light weight web material. An incoming sheet of material is slit into narrow webs, which may be folded by a folding guide, and separated by use of turning bars and guides. The narrow webs then enter an embossing or laminating station. The lamination process joins the two sheets which are of different widths to allow the process to produce stock for different final products. The laminate of folded webs and polymer may be slit and/or unfolded prior to being stored on a take-up reel.

Abstract: A method for producing a film with attached fibrils having a cloth-like look and feel. A flocking or metering device is provided for dispensing a layer of the fibrils. The fibrils are next delivered onto a moving vacuum belt, which has a porous surface for drawing the layer of fibrils thereto. After dispersion, the fibril layer is transported and held by the vacuum conveyor belt to a position under a slot cast extrusion die, where a lower temperature melt polymer is released. Upon release, the lower temperature melt polymer and fibril layer fuse and combine to interlock to create a composite temporary web. In one embodiment, the fibril layer and lower temperature melt polymer are delivered at a first nip point between a pair of nip rollers to create the composite temporary web. The composite temporary web may next be collected on collection rolls, or combined with a higher temperature melt polymer under a second slot cast extrusion die to form a permanent film with fibrils.

Abstract: A method for manufacturing rough-surfaced plastic sheet is based on technique, using cooperative extrusion by means of two or more extrusion machines. A main extrusion machine is for forming a main body of a plastic sheet. One or two auxiliary extrusion machine are for forming one or two rough-surface layers with plastic material, pigment and processing agent, which are melted and mixed together inside to let the foaming agent in the barrel generate bubbles and explode at the same time to form the plastic into one or two rough-surfaced layers. Then, after the main body and the rough-surfaced together pass through a mold head, the rough-surfaced layer adheres to one or two outer surfaces of the main body, cooled at once to form a plastic board with one or two rough surfaces, thus heightening producing efficiency, lowering investment coat and elevating competitive force.

Abstract: The present invention is an improved method for making a golf ball. Two cups are molded from an elastomer separately from a center. The cups are molded on both sides of a center mold plate with hemispherical protrusions having a channel circumventing the protrusions to capture excess cup material. The material in the channel aids in centering of the hemispherical cavity and allows the reduction or elimination of reinforcing polymer material. The protrusions force the elastomer cup material into cavities in outer mold plates on either side of the center mold plate, thus forming cups with cavities. The solid or fluid-filled center is placed within the cup cavities, and the cups are joined, preferably by raising the temperature of the mold above the cure activation temperature of the cup material.

Abstract: A method and apparatus for making a dripper line by feeding the dripper units (DU) into the extruded tube (ET) at a linear velocity, at the instant of their initial contact with the inner surface of the tube, which is greater than the linear velocity of the inner surface of the tube where initially contacted by the dripper units. The dripper units are fed between a track (10) within the extruded tube and a moving backing surface (20) externally of the tube spaced from the track to determine the final thickness of the extruded tube and the dripper unit welded thereto.

Abstract: A new fiber-forming method, and related apparatus, are taught in which extruded filaments of fiber-forming material are directed through a processing chamber that is defined by two parallel walls, at least one of which is instantaneously movable toward and away from the other wall; preferably both walls are instantaneously movable toward and away from one another. Movement means provide instantaneous movement to the at least one movable wall. In one embodiment, the movement means comprises biasing means for resiliently biasing the wall toward the other wall. Movement of the wall toward and away from the other wall is sufficiently easy and rapid that the wall will move away from the other wall in response to increases in pressure within the chamber but will be quickly returned to its original position by the biasing means upon resumption of the original pressure within the chamber. In another embodiment the movement means comprises oscillating means for oscillating the wall at a rapid rate.

Abstract: A method and apparatus for laminating a decorative lamination film to an extruded substrate is disclosed. The decorative lamination film may be clear, translucent, pearlescent, or opaque and it is compressed against the extruded substrate between a pair of rollers. In the context of vertical blind louvers, the rollers and the decorative lamination film are wider than the extruded substrate, the side edges of the extruded substrate being temporarily pressed upward in contact with the lamination film. The roller in contact with the lamination film is heated to a temperature sufficient to melt a central length of the lamination film that is contact with the extruded substrate, and thereby under increased pressure, but not so hot as to melt the unused side lengths of the lamination film. The unused side lengths, therefore, do not melt and naturally separate from the central length.

Abstract: This method consists essentially in manufacturing dripper units (4) and attaching them longitudinally to a thread (16) by positioning them at intervals along the latter. For this purpose, the thread (16) is introduced into at least one notch (9) of the dripper unit (4) so as to clamp it. The width of the notch is less than the diameter of the thread. The thread fitted with dripper units is introduced into the tube (1) while the latter is being formed in an extruder so as to draw the dripper units (4) therein one after the other. The dripper units are then heat welded to the inner wall of the tube during its formation. The insertion of the thread (16) into the notch (9) is achieved via a wheel (18) onto whose the edge it is guided. In this manner, the whole method can be implemented continuously without any intermittent operations.
