Discrete male touch fastener elements are molded of thermoplastic resin extending from a common, flexible base sheet, by introducing molten resin to a molding nip between two counter-rotating rolls consisting of a mold roll and a pressure roll arranged such that their rotation axes are parallel and together define a common plane containing each of the rotation axes. Solidified resin is stripped from molding cavities of the mold roll after the cavities have passed a rotating reaction roll forming a pressure nip with the mold roll. The reaction roll is spaced from the pressure roll by a distance less than an outer diameter of the mold roll, and the mold roll is simultaneously held against both the pressure roll and the reaction roll in a non-planar roll stack.

An apparatus for producing a microporous plastic film comprising a pattern roll having large numbers of high-hardness, fine particles; an anvil roll opposing the pattern roll; a conveying means for passing a plastic film through a gap of both rolls; a stationary frame rotatably supporting one of both rolls; a pair of laterally arranged movable frames rotatably supporting the other roll; and a pair of laterally arranged carriages to each of which each of the movable frames is fixed; at least one of the carriages moving in a running direction of the plastic film to generate positional difference between a pair of the movable frames, so that the center axes of both rolls are relatively inclined to each other.

An expansion ratio detection system for rubber, including a controller, a rubber sampling module, a rubber calender, a temperature control module, and an expansion ratio detection module. The rubber sampling module obtains a rubber to be tested consistent with a weight value. After the temperature control module determines that the rubber to be tested has reached a first temperature value, the rubber calender outputs the rubber to be tested having a thickness value. The expansion ratio detection module obtains an expansion ratio according to twice the thickness value and a roller pitch.

A molding apparatus defining a processing direction includes multiple molding modules spaced apart in a lateral direction perpendicular to the processing direction and a common reaction surface. Each molding module includes a frame and a mold roll that defines molding cavities. Each mold roll defines a respective pressure zone in cooperation with the reaction surface and each mold roll is movable with respect to the reaction surface by controlled operation of the frame. Molten resin is introduced into the pressure zones and forced into the molding cavities to form arrays of fastener elements extending from base layers of resin formed on the surfaces of the mold rolls. The fastener elements are withdrawn from the cavities while stripping the base layers from the peripheral surfaces.

A roll stack for the production of plastic sheeting uses a pneumatically-operated toggle joint, instead of a hydraulic press, to precisely separate two rollers. The pneumatically-operated toggle joint allows the rollers to be more quickly and safely further separated from each other in case there is an emergency.

A method is provided for manufacturing recyclable environment-friendly organic paper, in which a biomass plastic material, which is one of a biodegradable plastic (such as PLA), a biobased plastic (such as NPP), and a mixture of the two is used as a primary raw material, and the biomass plastic material and an inorganic mineral material (such as inorganic glass powder, mineral powder, and sand) and a bioplastic assisting agent (such as starch, apple pulp, egg shell, and the likes) are directly deposited into a compression and extension paper making machine to make environment-friendly organic paper. The environment-friendly organic paper so made does not contain fossil organic material (such as polypropylene), and thus no high temperature, smoke, and toxicant gases will be generated during burning and combustion and residuals of burning and combustion are primarily the natural inorganic minerals fraction can return to the earth and the nature.

A linear actuator leverage assembly including a base with a side surface and a back surface defining between them a corner, a rail member coupled to the base, a lever arm with a bearing surface, and a linear actuator. The lever arm is pivotally connected to the rail member at a first pivot and to the linear actuator at a second pivot. The linear actuator is configured to move the rail member with respect to the base over a linear stroke of the linear actuator that moves the second pivot of the lever arm along a continuous motion path. The motion path includes a first path segment generally parallel to the side surface and a second path segment, over which the lever arm pivots about the bearing surface as a fulcrum, thereby increasing leverage applied by the actuator to the rail.

A thin film member forming device includes a reference roll fixedly disposed while being rotatably supported by a first bearing member, a movable roll disposed movably with respect to the reference roll while being rotatably supported by a second bearing member, a roll gap adjusting mechanism which adjusts a gap between the reference roll and the movable roll and a roll opening mechanism which expands the gap. The roll gap adjusting mechanism adds a load in a direction to narrow the gap to the second bearing member, and the roll opening mechanism adds a load in a direction to expand the gap to the second bearing member.

A device of adjusting registration of plastic flooring contains a rolling unit and an adjusting unit. The rolling unit includes a press roller set having a first press roller, a second press roller, a third press roller, and a fourth press roller. The rolling unit delivers a substrate, a printing layer, and an anti-abrasion layer to the press roller set so as to be pressed together by the third and fourth press rollers. The printing layer has a pattern area, and the third press roller has a pressing pattern section. A first end of each of the third and fourth press rollers is connected on a fixed segment, a second end of each of the third and fourth press rollers is connected on a movable segment, and the adjusting unit is fixed outside the movable segment. The adjusting unit includes at least one power source and a movable rod.

The invention relates to a method and facility for manufacturing a tape of reinforcement filaments impregnated by a polymer matrix, as well as a tape produced thereby, said tape having a constant width across the entire length thereof, wherein the filaments extend in a direction parallel to the length of the tape, from a strand of filaments coming from a feeding reel. The method including steps and units that make it possible to manage the unwinding tension of the strand, to guide the strand on the axis of the machine, to manage the width of the strand, to deposit the polymer on the strand by electrostatic powdering, with a polymer weight ratio of around 20% to around 75% to melt the polymer, to calibrate the width and thickness of the tape and to collect the tape on the storage reel.
