  • Patent number: 11453279
    Abstract: 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.

  • Patent number: 10914385
    Abstract: 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.

  • Patent number: 10639832
    Abstract: 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.

  • Patent number: 10399813
    Abstract: A device for receiving an extruded elastomer strand, during the transport thereof to a processing location, including a reel that receives the elastomer strand as a winding, wherein the moving reel is provided for temporary inclusion into a production facility that continuously processes the elastomer strand, by rotation of the reel, to form seals for doors or boots of vehicle bodies. The average thickness of the reel resulting from the total mass and the total volume of the material of the reel is <2.5 g/cm3.

  • Patent number: 10065487
    Abstract: A method for forming seals on vehicle bodies produces by extrusion a sealing material strand to be processed to form a multiplicity of seals, coils the sealing material strand to form a transportable unit, transports the transportable unit to a processing site, and supplies the sealing material strand continuously at the processing site using the transportable unit to a processing device which forms the seals, wherein, within the scope of the processing, a portion of the sealing material strand to be applied to the relevant seal support seat and forming the seal is severed from the sealing material strand in each case.

  • Patent number: 9950894
    Abstract: 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.

  • Patent number: 9835251
    Abstract: A sealing strand for producing a seal by connection of the sealing thread with a strand seat that extends along a gap to be sealed, wherein the sealing strand has a tape region provided for bonding to the strand seat. During stretching of the sealing strand in the longitudinal direction of the strand, the tensile stress corresponding to the stretching in the tape region is at least partly compensated or capable of being compensated. This is achieved by the strand region being connected under compression with the remaining sealing strand.

  • Patent number: 9738145
    Abstract: A method for forming a seal or cover on an opening of a vehicle body. An extruded strand made of an elastomer material is adhered to a body support surface which receives the strand, and the support surface and/or a strand surface to be adhered is supplied with adhesive material prior to the adhesion process. The supply of adhesive material is controlled according to an adhesive material quantity requirement based on the strand length, the requirement changing in the longitudinal direction of the support surface, as a result of depressions and/or steps for example, and/or according to an arrangement of the strand surface to be adhered on the strand, the arrangement changing in the longitudinal direction of the support surface.
