A 3D thermoplastic pultrusion system and method based upon a 3D variable die system and including one or more sets of 3D thermoplastic forming machines to continuously produce thermoplastic composite pultrusions with at least one of varying cross-section geometry and constant surface contours, varying cross-section geometry and varying surface contours, and constant cross-section geometry and varying surface contours. The 3D thermoplastic pultrusion system and method including at least one of multiple pairs of shapeable and flexible bands and a rotating assembly that rotates the one or more sets of 3D thermoplastic forming machines to impart a twist to the thermoplastic composite.

Thermoplastic laminates are fabricated in a continuous compression molding production line. A lay-up of laminate plies is placed in a recess on a carrying tool, and the tool is moved through successive forming operations on the line, including preforming and consolidation operations. The tool is separated from the fully formed part at the end of the line and may be reused. Use of the carrying tool reduces material scrap.

The invention relates to a process to make films and tapes from ultrahigh molecular weight polyethylene (UHMWPE) in the solid state. The films and tapes according to the invention have an improved thickness whereby the coefficient of variation of the thickness of the film of at most 6%.

An air/gas filter medium is comprised of a substantially homogeneous core layer of feather down clusters held together by a binder to form a 3-dimensional interconnected filament structure throughout the core. The filament structure forms air pocket and connect and trap the feather down clusters which form minute air pockets between its filaments and hairs in which undesirable substances from an air/gas flow therethrough are captured. An air permeable scrim sheet is retained on a surface of the down cluster core. The down cluster core is compressed to a predetermined density to modify the average size of said minute air pockets to trap known undesirable substances from the air/gas flow.

A format compensator for a pressing device, comprising a compensating element (7) of a given thickness (S), structured so as to be interposed between the lower punch and the upper punch (10, 11) of a pressing device so as to be arranged in contact with the punches (10, 11) during pressing.

A double belt press having a first, lower circulating plastic belt and a second, upper circulating plastic belt. The plastic belts have a first, low flexural strength, and a product gap is formed between facing strands of the plastic belts for forming a plate-like product. A first circulating lower steel belt and a second circulating upper steel belt are provided and have a second flexural strength which is high in comparison to the flexural strength of the plastic belts. A forming section is formed between the facing strands of the steel belts, which forms part of the product gap. The first, lower steel belt runs parallel and bears against a rear face of the first plastic belt in the forming section during operation, and the second upper steel belt runs parallel and bears against a rear face of the second plastic belt in the forming section during operation.
