摘要:
A sealing strand, in particular for processing during continuous feeding and separation of use portions, including multiple strand parts each of which are connected to one other at abutting ends, and including a double-sided adhesive tape. A removable protective strip covers the tape adhesive surface facing away from the remaining sealing strand. The protective strip has a butt strap at each of the butt joints. The butt strap overlaps the abutting ends of the protective strip portions of the strand parts. Each connection between the butt strap and the overlapping abutting ends of the protective strip portions of the strand parts begins only at a distance from the butt joint. The connection of the butt strap to at least one of the two overlapped abutting ends begins in a region in the strand longitudinal direction of consecutive separating cuts in the abutting end.
摘要:
A method for preparing extruded material for processing to form sealings and/or edge protection strips on vehicle bodies, where the extruded material to be prepared, which is substantially of an elastomer substance, includes a covering strip protecting an adhesive layer and extending in the longitudinal direction of the extruded material. The covering strip has sub-sections that are connected to each other on the abutment ends thereof. The covering strips are detached from the adhesive layer and are reconnected to the adhesive layer, optionally in such a way that they are offset to the longitudinal direction of the extruded material. If the offsetting is carried out, the abutment ends of the sub-sections of the covering strip are arranged such that they are offset in relation to the original position thereof on the adhesive layer.
摘要:
A method for forming seals on seal carriers, in particular vehicle doors or vehicle door frames, extrudes a sealing material strand which is to be processed to form a multiplicity of seals and has a cavity, coils or folds up the sealing material strand, forming a transportable unit that is transported to a processing site and the sealing material strand is fed continuously to a processing device by being drawn out of the transportable unit. During the processing, a section of the sealing material strand that is to be applied to the relevant seal carrier and forms the seal is in each case severed from the sealing material strand. In each case during or after the processing of the sealing material strand to form a seal, that section of the sealing material strand which forms the seal is reinforced in places at least at one predetermined longitudinal position of the section by introducing material into the cavity.

A device for receiving an elastomer strand, in particular a sealing strand, that is to be conveyed to a processing location, and for feeding the elastomer strand at the processing location to a device for separating pieces from the elastomer strand and processing them, has a roll that receives the elastomer strand in the form of a coil, a conveying container that receives the roll with the coil and systems for rotating the roll within the conveying container in order to unwind the elastomer strand from the roll and feed it to the processing system. The conveying space required for the device after the elastomer strand has been unwound from the roll can be reduced.
