A method and apparatus for a continuous compression molding machine. The continuous compression molding machine comprises a tooling die, extending through a heating zone and a cooling zone, a tooling sleeve, and a biasing system. The tooling sleeve corresponds to the tooling die and is for use in forming a thermoplastic composite part from a thermoplastic composite charge when the tooling sleeve with the thermoplastic composite charge is moved with respect to the tooling die through the heating zone and the cooling zone. The biasing system is configured to hold the thermoplastic charge at a first angle within the heating zone and hold the thermoplastic composite charge at a second angle within the cooling zone, as the tooling sleeve moves through the heating zone and the cooling zone with the thermoplastic composite charge. The first angle is different from the second angle.

A molding tool and a method for producing molded parts from a moldable material with at least one first tool component and at least one second tool component are described. The first tool component has a cavity with a first molding surface and the second tool component has a molding element with a second molding surface, which has an at least partially flexible material. Moldable material introduced into the cavity is pressed against the first molding surface at least in certain regions by the deformation of the flexible material. A medium is introduced via the molding element for this purpose, which leads to deformation of the flexible material.

Sheet having fastening elements, comprising a base strip made of thermoplastic material and at least one element made from the strip, the element consisting of a stem extending in a transverse, in particular vertical, direction to the plane of the base strip, and having a cross section which is substantially uniform or decreases from the base strip towards the apex of the stem, in particular as far as the apex of the stem, and a part forming a head which protrudes laterally from the apex of the stem.

A system for the continuous extrusion, molding, and curing of tread for tires. An elongated strip of rubber material can be molded and cured shortly after extrusion such that the material retains much of the heat energy of extrusion and does not have to be stored. A plurality of discrete mold assemblies are conveyed adjacent to each other. As the mold assemblies are advanced sequentially, the uncured and unmolded strip of rubber material are extruded and positioned onto the mold assemblies. While the rubber strip advances, individual portions are sequentially molded and cured by passing through a mold press and then a curing press. A plug assembly is used to prevent the backflow of rubber material during the molding and curing.

The present invention relates to a hot plate structure of a press molding device, and a continuous molding method using the same. The continuous molding method continuously performs primary and secondary overlapping molding operations on the basis of a length unit which is smaller than a set length unit (cutting width) and accordingly cancels out a boundary part, thereby being capable of improving the thickness difference of the boundary part and thus enabling uniform physical properties to be obtained. The hot plate structure comprises a protrusion part which protrudes by lengthening both sides of a hot plate to the outside of a chamber, wherein the protrusion part is formed at a thinner thickness than the thickness of the hot plate within the chamber so that the pressure and temperature applied to the protrusion part are lower than the pressure and temperature applied through the hot plate within the chamber even if the molding operations are performed with the same time and conditions (pressure, temperature, etc.), whereby due to air cooling and temperature control effects, sheet transformation can be inhibited and bubbling can be controlled during the continuous operations through the aforesaid secondary overlapping molding operation.

A packaging machine is for forming a product cavity in a web including a forming die box defining a recess into which the product cavity is formed. An insert is axially movable in the recess to thereby vary a depth of the recess. A variable depth mechanism selectively moves the insert to vary the depth of the recess. The packaging machine includes a latching mechanism that moves the forming die box into and between a first position in which the forming die box is spaced apart from the die box base and a second position in which the forming die box is supported by the die box base.
