The belt calender includes auxiliary rollers which are rotatable around their longitudinal axes, and are arranged substantially parallel to the first roller around at least a part of a circumference thereof. The first and second belt run in between two adjacent ones of the plurality of auxiliary rollers, thereby defining a meandering path for the feed of material. A method for manufacturing preimpregnated composites by using such a belt calender.

A vehicle door molding includes a core member and a resin material. The resin material includes a curved surface as viewed in a cross section orthogonal to a longitudinal direction of the vehicle door molding. A method for manufacturing the vehicle door molding includes covering a surface of the resin material with a film during transfer of the core member on which the resin material is disposed. The method further includes pressing an entire surface of the film with pressing members during transfer of the core member on which the resin material is disposed. The pressing is performed following the covering with the film. The pressing members are arranged at positions differing from each other in a transfer direction and a direction intersecting with the transfer direction. The method further includes separating the film from the resin material after the pressing.

A method of forming a retaining device with hooks, wherein: a molding strip is provided that presents an inside face and an outside face, and that has a plurality of cavities, each cavity defining a stem extending from the outside face towards the inside face and including an end forming a head that extends from the stem towards the inside face of the molding strip; and the molding strip is positioned on rotary drive means, comprising at least two rollers, the inside face of the molding strip being arranged to bear against the drive means.

A retaining device, comprising: a base (51) extending in a longitudinal direction and presenting a top face (511) and a bottom face (512); and a plurality of retaining elements extending from the top face (511) of the base (51), each of the retaining elements being formed by a stem (52) surmounted by a head (53), the stem (52) having a bottom end (521) connected to the base (51), and a top end (522) opposite from the bottom end (521), the head (53) surmounting the top end (522) of the stem (52), and having a bottom face facing towards the base and a top face opposite from the bottom face.

A molding apparatus (10) for forming a retaining device. The molding apparatus (10) comprises a molding strip (12) and a molding support (24). The molding strip (12) has an inside face (14), an outside face (16), and a plurality of through cavities (18) extending from the outside face (16) to the inside face (14), the molding strip (12) extending in a longitudinal direction (X) and presenting both a transverse direction (Y) perpendicular to the longitudinal direction (X), and also a height direction (Z) perpendicular to the longitudinal direction (X) and to the transverse direction (Y). The inside face (14) is configured to press against a molding face (26) of the molding support (24), wherein the inside face (14) of the molding strip (12) and/or the molding face (26) of the molding support (24) includes an array of passages, the array of passages forming vents and connecting together the cavities (18) when the molding strip (12) is pressed against the molding support (24).

A method for controlling the thickness of a continuous elongated element made of elastomeric material, applied according to coils wound on a forming support, includes: advancing a head end of the continuous elongated element toward the forming support; subjecting, during the advancement, the continuous elongated element to a first stretching with a first stretch coefficient before applying on the forming support; and subjecting, during the advancement, the continuous elongated element to a second stretching with a second stretch coefficient during the application on the forming support. During the first stretching, a span of the continuous elongated element adjacent to the head end is stretched with a supplementary stretch coefficient greater than the first stretch coefficient, in a manner so as to confer, also to the span adjacent to the head end, a stretch and a section similar or substantially equivalent to those of the rest of the continuous elongated element.
