A device for welding thermoplastic tubes to a welding method, and to a welding knife. The device is provided for welding thermoplastic tubes, wherein the tubes are placed into tube holders and squeezed with the aid of tube clamps. A welding knife is moved between the first and the second tube holder and severs the tubes in the process. Cut ends and residual ends are thereby produced. The cut ends are aligned with one another by a relative movement of one tube holder with respect to the other tube holder and, by a horizontal movement of the two tube holders, are welded simultaneously to form continuous tubes.

Interlaminar features of a composite structure are laid up by placing and steering individual chopped fiber pre-preg segments onto a substrate.

A method of producing a multi-layered absorbent articles having two or more colored regions is described. The method includes the steps of: providing an absorbent article converting line; supplying a first material web to the converting line; supplying a second material web to the converting line; printing a first colored region on at least one of the first material web or the second material web using contact printing at a contact printing station; and printing a second colored region on at least one of the first material web or the second material web using non-contact printing at a non-contact printing station. The first colored region has an arcuate shape.

A lamination system includes a sheet supply, a material supply, and a laminator. The laminator causes a sheet from the sheet supply to be laminated to a sheet from the material supply to establish a laminated sheet.

A method for producing a composite multi-layered absorbent article. At least two of the layers include a colored region.

A lamination system includes a sheet supply, a material supply, and a laminator. The laminator causes a sheet from the sheet supply to be laminated to a sheet from the material supply to establish a laminated sheet.

There is disclosed a composite material lay-up head (20) for applying elongate fibre reinforcement material (14) to a tool (12), the head (20) comprising: at least one elongate tow guide channel (32) for guiding fibre reinforcement material (14) from a tow inlet (33) to a tow outlet (35) of the channel (32); and feed apparatus (36, 38) for feeding fibre reinforcement material through the at least one channel (32); wherein the or each channel (32) is provided with at least one nozzle (60) arranged so that in use a jet of gas can be delivered into the channel (32) so as to inhibit contact between fibre reinforcement material (14) in the channel (32) and the channel (32).

A reinforced stretch film obtained by a method of producing a reinforced stretch film comprising the steps of: providing an elongated base sheet of plastic stretch film having a longitudinal axis, forming a plurality of cord-like, elongated reinforcement members and a plurality of plastic film strip overlays, positioning the plurality of elongated reinforcement members on the elongated base sheet, positioning a single plastic film strip overlay over each of the elongated reinforcement members, folding each edge of the elongated base sheet inward toward a center of the elongated base sheet to further strengthen and reinforce each edge and attaching the plastic film strip overlays and the folded edges to the cord-like, elongated reinforcement members and to the elongated base sheet to fixedly sandwich the cord-like, elongated reinforcement members between the elongated base sheet and the narrow plastic film strip overlays.

Disclosed is an assembly manufacturing method comprising: cutting a prepreg into a prepreg sheet according to a first parameter; moving the prepreg sheet to an assembly arrangement area according to a second parameter; superimposing a metal foil and a plate according to a fourth parameter to form a copper foil set; and assembling the copper foil set and the prepreg sheet according to a third parameter to form an assembly.
