摘要:
A method produces a supporting web made of a predeterminable amount of plastic material having a multitude of molded elements molded inside mold cavities (12) of a forming tool (5). While applying a negative pressure at least in one portion of the cavities (12), enough plastic material is always applied to the mold wall (13) of the respective mold cavity to form a cavity (22) inside the molded element. A supporting web has a multitude of molded elements produced by using this method.
摘要:
Method for the production of an adhesive closure device together with an apparatus and adhesive closure device produced accordingly. The invention relates to a method for the production of an adhesive closure device (10), preferably consisting of at least one plastic material, during which a backing (12) with a plurality of protruding stems (14) is connected to individual heads (16) in such a way that for at least a part of the above-mentioned stems (14), the free ends (18) thereof come into contiguous or embedded contact with a contact face (20) of each assignable head (16). The invention relates additionally to an apparatus for carrying out the method and to an adhesive closure device produced according to the method.
摘要:
A closing mechanism (1; 101; 201; 301) includes a plurality of closing elements (2; 102; 202; 302; 302a) such as hooks, mushroom heads or loops, and a flat carrier (3; 103; 203; 303). The closing elements (2; 102; 202; 302; 302a) protrude from at least one surface (4) of the carrier (3; 103; 203; 303). The closing mechanism (1; 101; 201; 301) has a heater (5; 105; 205; 305), at least in certain sections, which converts supplied energy into heat. The invention also relates to an associated production method.
摘要:
The invention relates to a surface for an article that has an artificially producible base structure (10). The respective structure (12) has or develops a capillary effect at which the quotient from capillary work (K) and adhesion work (A) is larger 1. The capillary structures and their respective capillaries therefore have a so-called negative capillary rise, that means that liquid is forced from the capillaries, thereby allowing for a self-cleaning effect.
摘要:
A contact closure component (10) includes a carrier part (12) and closure parts (14a-14b) arranged upright on the carrier part. Each closure part (14a-14b) has at least one stem part (10a-20b) having a pre-definable longitudinal extent (Hs). At least one shaping section (26a-26b) is formed on at least one stem part (20a-20b), in at least one length section (24a-24b). The shaping section is set back at least partially with respect to an imaginary stem outer shape, in the direction of the interior of the stem. At least one shaping section (26a-26b) permits elastic deformation and/or movement longitudinally and/or transversely with respect to the longitudinal extent (Hs) of the respective stem part (20a-20b).
摘要:
An adhesive closure piece (10) includes a substrate part (12) and closure pieces (20a, 20b) of at least one type arranged upright on the substrate part. The closure pieces each have a head part (14a, 14b) having at its free end face at least one contact surface (22a, 22b) for detachably adhering to another component by adhesive force. The closure piece has at least one connection section (16a, 16b) on the edge of each head part (14a, 14b). The connection section protrudes beyond the edge of the head part (14a, 14b) in at least one direction (30, 36) such that the size of the contact surface (22a, 22b) of the corresponding head part (14a, 14b) is changed.
摘要:
The invention relates to a support device for improving the haptics and/or gripping impression of humanoid or android type hands. Said device comprises an active surface that interacts with parts (16, 18, 22) of the respective hand to carry out a movement and that has individual, stem-like projections, each comprising a free end face such that said projections at least partially improve the adhesion of at least parts of the hand or of a hand protector (10) to surfaces, particularly smooth or delicate surfaces, that are touched. Said invention is characterised in that the respective free end faces (26) of said projections (24) are designed in such a way that the adhesion thereof results from acting van der Waals forces between said free end faces (26) and the respective surface.
摘要:
A touch fastener has a plurality of interspaced bonding elements arranged on a backing. Each element has a head (12) connected to the backing by a stem (14). To allow the head (12) to always remain fastened to a body in the immediate vicinity, even if the backing is axially displaced over a predeterminable distance on a plane extending parallel to the body, the head (12) has a disc with a diameter greater than the diameter at any point on the stem (14). The stem is conical and connected to the disk in an articulated manner by an articulated part (16).
摘要:
A closing device (1, 101, 201, 301) includes a plurality of adhesive closing elements (2) in the form of a hook, mushroom head or clasp, and a flat support (3, 103, 203, 303). The adhesive closing elements (2) protruded from at least one surface (4) of the support (3, 103, 203, 303). At least one switching circuit (5, 503) with at least one electric and/or electronic component (6, 106, 7, 107, 207, 307) is provided.
摘要:
A method produces a support web (10) made of a predefined amount of plastic material by a plurality of molding elements (16, 17) formed in hollow spaces (12) of a mold (5). The plastic material is fed to the mold (5) via at least one extruder nozzle (1) of an extruder apparatus (18). To be able to lower the processing temperature while the plastic material obtains a very good molding behavior into the hollow spaces of a mold, the plastic material is intrinsically provided with at least one additive such that the melt flow index (MFI) of the plastic material remains constant or preferably increases.
