The present invention concerns a device (1) for applying gripping handles (M) on films (P), being supplied on shrinkwrap packers (2) for making bundles of bottles (B), cans and/or similar containers (B). The device (1) comprises: an applying head (10) provided with a roller (11) for applying gripping handles (M); an abutment mechanism (14) for operatively supporting a series of heat-shrinkable packaging films (P), being supplied on a respective shrinkwrap packer (2). The applying roller (11) and the abutment mechanism (14) are mobile with respect to one another between a non-operating condition, in which they are spaced apart, and an operating condition, in which the applying roller (11) is arranged, at the abutment mechanism (14), against at least one of the films (P) being supplied to apply a respective gripping handle (M) on the latter. The abutment mechanism (14) comprises a supporting tape (15) having an advancement surface (16) for advancing the films (P), which, in the operating condition, provides an abutment for the applying roller (11), which applies each handle (M) on a respective packaging film (P), acting against the advancement surface (16) of the supporting tape (15).

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

A system fabricating composite preforms includes a layer assembly stage with a first stage for receiving new layers, such as layer N; and a second stage for holding up to K layers, such as layers N1 to NK. An interlayer reinforcement insertion mechanism inserts interlayer reinforcements Q through layer N and the layers N1 to NK, using a first layer spacing between layer NK and layer N-K1 in a completed layer stage. Following the interlayer reinforcements Q insertion, the layer assembly stage transfers the layer NK to the completed layer stage; closes the first layer spacing, bringing layers NK and NK1 into contact; and transfers the layer N to the second stage. The system repeats this cycle of receiving new layers, inserting interlayer reinforcements using layer spacings between the second and completed layer stages, closing these layer spacings, and transferring layers to construct composite preforms with arbitrary numbers of layers.

A bamboo composite material for structural applications and method of fabricating the same are provided. The method can comprise the steps of providing a bamboo culm; separating a slice or sheet from the bamboo culm such that the slice or sheet has a longitudinal axis along a fiber direction of the bamboo culm; at least partially detaching individual fiber bundles of the slice or sheet from each other along the longitudinal axis of the slice or sheet; applying a glue to the slice or sheet; and curing the glued slice or sheet.

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.
