Abstract: An industrial-sized briquetting press having two independent bearing housings for supporting the drive shafts of the briquette-forming rolls. One of the bearing housings is rigidly mounted and the other is pivotally mounted to the first by a pivot located midway between the longitudinal axes of the drive shafts. The axes are substantially parallel and the pivotally mounted housing moves in the plane of the axes. The rolls are biased together by hydraulic cylinders. Connecting rods attached to the rigidly mounted bearing housing, slidably passing through the pivotally mounted bearing housing and hollow piston rods of the hydraulic cylinders, and supporting the hydraulic cylinders prevent movement of the briquette-forming rolls in relative longitudinal and lateral directions. The press has no overall frame permitting easy access for repair and maintenance and the pivot is demountable permitting removal of the pivotally mounted bearing housing.

Abstract: This invention concerns an apparatus for embossing a plastic workpiece using vibratory energy. A workpiece to be embossed is brought into forced engagement with indicia carried by an embossing ring which is disposed at or in proximity to the antinodal region of longitudinal motion of a resonator. The resonator is caused to vibrate at its natural frequency of oscillation in a direction substantially parallel to the workpiece surface. After embossing the workpiece is removed from contact with the resonator.

Abstract: Synthetic resinous thermoplastic tubing is reduced radially in diameter with minimal increase in length by passing the tube through a plurality of successively smaller dies wherein a minor portion of the die moves relative to a major portion of the die during the reduction step. Plastic tube is obtained which has a tendency to expand radially with a minimal alteration in its length. Such tubing is particularly suitable for lining of pipe.

Abstract: The present granulating apparatus is especially suitable for chopping strands or thermoplastic material into small pieces as the strands emerge from nozzles. For transporting these strands when they are still hot and partially liquid from the nozzles to a cutting apparatus, there is arranged a chute between the nozzles and a pair of feeding rollers just upstream of the cutting apparatus. The feeding rollers exert a slight pull on the strands. The chute has an entrance end or inlet and an exit end or outlet, as well as a chute path interconnecting said ends, said chute path protruding at least at said ends from a common plane defined by the nozzles and by said feeding rollers, whereby the strands are pressed against the chute at least at the chute ends. A housing surrounds the cutting roller. Cooling water supplied to the housing is divided into a main stream and into a water curtain. The water curtain is so located that the cut off granules must first pass through the curtain before contacting the housing.

Abstract: Plasticizable material is pressure molded into articles free from flash in mold cavities of specialized molds defined by separate mold sections with removable cores. Prior to and during molding, the sections are held clamped together to fully confine the material which is pressurized by reducing the volumetric capacity of each cavity. This pressurization is maintained until the material is set or cured, and may be increased before final set to forge or densify the material further. The method employs a conventional press and two gangs of specialized two-piece, multi-cavity molds. The molds of each gang are supported in a horizontal row, with their juxtaposed flat faces and parting planes disposed vertically, for movement of each mold section flatwise endwise of the row to open and closed positions. The mold sections are clamped closed by power means which apply extraneous clamping pressure independently of the press operation.

Abstract: A mat formed of a mixture of board particles and a bonding agent is conveyed to oppositely rotating rollers which compress said mat to a desired thickness as the mat passes therethrough. A conveyor associated with the rollers is provided for carrying the compressed mat between a pair of platens mounted in a fixed relationship with respect to the continuously moving mat. As it passes between the platens, the mat is supported by a fluid bearing and is exposed to heat to cure the bonding agent. The platens are internally divided into separate subcompartments. The pressure in these subcompartments is regulated such that the mat is subjected to controlled pressures as it moves past the platens.

Abstract: A board is formed by accumulating a mass of sugarcane rind fibers in a collection zone ahead of a horizontally reciprocable first-stage plunger that has a sweep face. The first-stage plunger is shifted horizontally toward a fiber compression zone to horizontally compact the sugarcane rind fibers and orient the fibers in vertical planes disposed substantially parallel to the sweep face. A second-stage plunger is shifted vertically downwardly from above the compression zone to push the horizontally compacted sugarcane rind fibers downwardly into a generally vertical passage means while vertically compressing the fibers. Consequently, the fibers are oriented in substantially horizontal planes to define a board segment comprised of sugarcane rind fibers having their axes disposed substantially parallel to the longitudinal axis of the board segment. The steps of accumulating, horizontally shifting, and vertically shifting are repeated to establish a column of abutting board segments in the extrusion passage.
