摘要:
A dual roll fabric welding or seaming machine is configured to seam pieces of sheet material to one another as the pieces move downstream. The machine includes modular gantries and various actor devices which may be readily mounted on any of the gantries to interact with the moving sheet material to achieve various functions, such as seaming pieces of sheet material together, forming hems, applying grommets to the sheet material, printing on the sheet material, connecting reinforcement strips or ropes to the sheet material and cutting the sheet material.

A joining apparatus includes a fusing mechanism part that joins two thermoplastic sheet-like materials by fusing, a sticking mechanism part that sticks an adhesive tape along a joined portion of the sheet-like materials, a workbench having a placement surface on which the fusing mechanism part and the sticking mechanism part are disposed side by side, the placement surface allowing the sheet-like materials in an unfolded state to be placed thereon, and a guide that allows an end portion to be joined of one of the sheet-like materials and an end portion to be joined of the other sheet-like material to overlap each other while aligned along a plane intersecting the placement surface, each of the end portions to be joined of the sheet-like materials being placed on the placement surface, and to feed the overlapping end portions to be joined. The fusing mechanism part fuses and joins the end portions.
摘要:
A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

A unit for forming absorbent sanitary articles including a drum rotatable about its axis of rotation and having a circumferential peripheral surface movable along a feed direction, first feeding means for feeding a succession of pairs of panels of material facing the circumferential peripheral surface and configured to position each pair in such a way that the respective two panels are facing each other and transversely aligned with the feed direction and second feeding means for feeding a continuous web of material suitable for defining at least part of the main body of an absorbent sanitary article, and configured to position the web on the circumferential peripheral surface of the drum in such a way that each panel projects partly sideways from the web. The unit comprises an ultrasonic sealing station located along the circumferential peripheral surface of the drum, in a zone located operatively downstream of the second feeding means, and configured to attach each panel of the pair to the web at at least one plurality of sealing points arranged in succession along the feed direction.
摘要:
A printed product is provided with a plastic film of a polymer composition containing at least partially polyvinyl chloride or polyolefin. The plastic film has a first face and a second face. A printed layer made of at least one color medium is printed onto the first face of the plastic film, wherein the printed layer is sealant-free and forms a user-side exterior face of the printed product. The second face of the plastic film is connected by material fusion to a support. The support has a material thickness of at least 1.5 mm and is made at least partially of a foamed and recyclable polymer composition. The printed layer is printed onto the plastic film in a quantity of 5 ml/m2 to 40 ml/m2 of the at least one color medium. The printed product has a surface roughness of at least 10 μm at the printed side.

摘要:
A belt splicer (80) for butt-welding conveyor belts with longitudinal walls and methods for splicing belts. The belt splicer (82, 83) has bridges supporting belt clamps (88) above clamp jaws (12, 13). The bridges are attached at opposite ends to the corresponding jaws. Slots (96) along intermediate spans of the bridges allow the belt clamps to be adjustable positioned along the bridges. Adjacent belt clamps can be positioned with a space between them to accommodate the walls.
摘要:
A method and apparatus for constructing a tubular assembly 40 comprising an inner portion (24) and a further portion (23) surrounding the inner portion. The inner portion (24) comprises reinforcement (37) and the further portion (23) being formed from a strip (50) of material comprising two opposed longitudinal marginal side portions (53). The apparatus comprises an assembly station (220) comprising a wall (253). The apparatus comprises means for advancing the inner portion (21) along a first path (231) extending passed the wall (253), and means for advancing the strip (50) along a second path (232) and causing the strip to encircle the wall (253) and thereby wrap about and surround the inner portion (21). The apparatus further comprises means (321) for introducing resinous binder into the reinforcement (37) as the strip (50) is being wrapped about the inner portion (21).
摘要:
Apparatus for shaping a segment of material includes a forming member having a curved sidewall shaped complementary to a desired shape of the segment of material, and a conforming member having an applicator side and an engagement side disposed for engagement with the curved sidewall of the forming member. The conforming member includes a plurality of attachment regions disposed on the applicator side. Each attachment region is adapted to hold the segment of material on the conforming member. Engagement of the conforming member with the forming member causes the attachment regions to move from a first shape profile to a second shape profile, the second shape profile being the desired shape of the segment of material.
