A cloth attachment device includes a frame, and further includes: a first roller arranged on the frame and capable of being rotated around its axis relative to the frame; a transmission mechanism arranged on the frame and capable of being moved relative to the frame, a to-be-attached cloth being arranged between the first roller and the transmission mechanism, two opposite surfaces of the to-be-attached cloth being in contact with a first position on the transmission mechanism and a second position on the first roller, respectively; and a driving mechanism configured to drive the first roller to rotate and drive the transmission mechanism to move in such a manner that the first position and the second position are moved in an identical direction, thereby to enable, through the transmission mechanism, the to-be-attached cloth between the first roller and the transmission mechanism to be curled up around the first roller.

A wiring apparatus includes a substrate, two winding modules, and an axial wire dividing module. The two winding modules are disposed on the substrate. Each winding module includes a clamping mechanism with a chuck, a rotary mechanism having a rotation driving unit driving the chuck; and a reciprocating mechanism with a rail-slider assembly, the rotation driving unit connected to the slider. The axial wire dividing module is disposed on the substrate and located between the two winding modules with a wire supply channel provided with a wire inlet and a wire outlet. The wire outlet is provided with a cutter aligned with the center of the wire supply channel, and a cutting edge of the cutter faces the wire inlet; a waveguide prototype mould is formed by dividing a wire in real time and winding wires in grooves of a waveguide prototype.

A method of manufacturing a tubular multilayer structure made from a continuous fiber pre-impregnated with a thermoplastic resin includes feeding the material to a shaping station before the material is wound around the mandrel. The material is heated over a shaped hot plate while in the shaping station to lightly melt the material. The material is tensioned to at least 15,000 psi before the material is wound around the mandrel to ensure good bonding of the wound layers.

Hollow fiber separation membranes are bundled in groups of 5-350 membranes and helically wound with a 20-120 denier yarn. The bundle is more readily handled when making permeators using dry membranes and there is significantly reduced fiber breakage and damage.
摘要:
A non-woven fabric web is converted to a tubular shape by forming the web between a cylindrical mandrel and surrounding sleeve, and passing reciprocating barbed needles through the region where the sides of the web abut each other, to form a butt joint thereat. The apparatus includes a pair of rollers for drawing the tubular shaped web between the mandrel and sleeve, as well as a motor and control circuit for operating the reciprocating needles.

This invention is concerned with apparatus for manufacturing spirally wound gaskets. The apparatus includes a pair of co-planar radially movable forming discs and independently mounted and axially adjustable guide members. The apparatus may be used either for winding gasket forming material tightly around one forming disc, or adapted for centerless winding where gasket forming material is wound in a loop around one forming disc. Where thin, wide-flanged gaskets are to be wound, the forming disc which abuts the outer periphery of the gasket is shaped so as not substantially to curve gasket forming material in the direction away from the gasket periphery and thus produce stress in the gasket. Where the apparatus is designed for centerless winding, a template adapted to be disposed between the forming discs to move in conjunction with gasket forming material may be provided, particularly for forming non-circular gaskets.
