Definitions

• the invention relates to a magazine strip comprising a plurality of fastening parts which follow one another at a spacing and are provided with at least one through opening which runs transversely to the longitudinal direction of the strip and which is embedded by at least one cord, a band or the like which is embedded in the material of the fastening part. are connected to one another consecutively at a constant distance.
• sealing disks for screws form parts of the magazine strip, these sealing disks being connected to one another at their mutually facing outer contours via narrow webs running parallel to the longitudinal extent of the magazine strip.
• These sealing disks are formed in one piece with the webs connecting them, the magazine strip being relatively rigid in such an arrangement and therefore can only be rolled up in one direction, namely in the plane guided by the axes of the fasteners used.
• Such magazine strips are only suitable for transport and packaging in a straight shape.
• a magazine strip has also become known (US Pat. No. 4,040,325), which consists of a large number of nails with hat-like heads that follow one another at a distance. A cord is guided along below the nail head, this cord being glued to the mutually facing edges of successive nail heads.
• a magazine strip can probably be produced, in which individual fastening parts are connected to one another by means of a cord, and it is also possible to roll such a magazine strip in different directions, but there is no problem with the magazine here of fastening parts provided with through openings, where yes the The passage opening must remain free for inserting or screwing in a fastener.
• the object of the present invention is therefore to create a magazine strip of the type mentioned at the beginning which can be rolled in a simple manner transversely to the axial direction of the fastening parts, and this despite passage openings provided in the fastening parts.
• the cord, the tape or the like or the cords, tapes or the like lies or lie in a plane seen in the longitudinal direction of the magazine strip, which leads through the through opening of the fastening parts, and that between the entry in the fastening parts and the exit from this section of the cord or cords, the band or tapes or the like is poured into the wall of the fastening part made of plastic including the through opening.
• a magazine strip according to the invention is therefore also particularly suitable for the magazine of approximately tubular fastening parts with screws or the like inserted directly therein, since the through opening in the fastening part itself for the mutual despite the at least approximately central arrangement of cords, bands or the like Keeping the fastening parts clear for inserting, inserting or screwing in further components remains free.
• At least one cord, one band or the like is assigned to the two end regions of the fastening parts in relation to their longitudinal extent. This measure is particularly expedient in the case of relatively long fastening parts, since these are then kept spaced axially apart, which is particularly important in the subsequent feeding of such magazine strips to an automatic screwing machine.
• One possibility of embedding the cord, the band or the like in the fastening part is that the section of the cord, the band or the like located between the entry into and the exit from the fastening parts on the inside or outside surface of the wall of the fastening part the surface course of which is cast in in an adapted manner. It is thereby possible to allow the inserted cord, the tape or the like to rest against the inner surface of the outer or inner shape, so that the cord, the tape or the like is firmly cast in during the injection molding process during the production of the fastening parts. even if it comes to rest along the inner or outer surface of the fastening part.
• the section of the cord, the band or the like located between the entry into the fastening parts and the exit therefrom is cast in approximately in the middle region with respect to the thickness of the wall of the fastening parts. It is possible that the cord, tape or the like lies loosely in the area between the inner and outer shape, since it is only essential that the distance between the successive fastening parts is maintained in a constant size.
• the fastening parts have different outer and / or inner dimensions when viewed in their longitudinal extent, so that the cords, bands or the like engaging at the two end regions of the fastening parts in the longitudinal direction of the magazine strip seen have a different overall length, but the fastening parts follow each other with parallel axes aligned to each other.
• the sections between the individual fastening parts on the two spaced-apart cords, bands or the like are of different lengths, and likewise the sections of the cords, bands lying within the wall of the fastening parts or the like be of different lengths if, for example, the inside and / or outside diameter of the fastening parts is different in size at the corresponding areas thereof. Nevertheless, there is the possibility that the fastening parts, aligned in parallel with one another, follow one another on the cords, bands or the like, cast on.
• the cord, the band or the like be made of a different material than the fastening parts, e.g. is made of glass fibers or glass fiber-like material, textile fibers, metal or metal fibers or the like.
• a suitable material can be selected depending on the intended use and the required tensile strength or the required ability to tear off or separate the cords, tapes or the like.
• the material of the cord, tape or the like is made of a material which ensures the perfect manufacture of a magazine strip and which withstands the high temperature which arises during the manufacturing process for the fastening part .
• FIG. 1 shows a magazine strip in side view.
• Figure 2 shows a section through a fastening part with an inserted screw in a longitudinal section.
• Fig. 3 is a plan view of two successive fasteners, the course of the cord used can be seen.
• the magazine strip 1 consists of a multiplicity of fastening parts 2 which are connected to one another by means of two cords 3 and 4 running at a distance from one another. These are fastening parts 2 which are provided with a through opening 5, a screw 6, for example, being able to be inserted into these fastening parts, so that the fastening parts 2 can be pre-stored together with screws 6.
• Such sleeve-shaped fastening parts 2 are used together with screws 6 for fastening thick insulating layers on roofs, a large-area washer being used during assembly below the widened upper end region 7 of the fastening parts 2.
• the cords 3 and 4 are embedded in the material of the fastening part 2, that is to say firmly connected to the fastening parts, so that the fastening parts 2 are successively connected to one another at a constant distance.
• the cords 3 and 4 lie in a plane 8 in the longitudinal direction of the magazine strip 1, which leads through the through opening 5 of the fastening parts 2 and, in the present particular case, through the center axes 9 of the fastening parts 2.
• the section 10, 11 of the cords 3 and 4 located between the entry into the fastening parts 2 and the exit therefrom is in each case cast into the wall 12 of the fastening part 2 including the through opening 5. This pouring takes place already during the manufacture of the fastening parts 2 made of plastic.
• a cord 3 or 4 is assigned to the two end regions 7 and 13 of the fastening parts 2 in relation to their longitudinal extent.
• the plane 8 also forms the central plane of the magazine strip 1 which is guided by the axes 9.
• the fastening parts 2 are provided with different outer and inner dimensions when viewed in their longitudinal extent, so that the cords 3 and 4 acting on the two end regions 7 and 13 of the fastening parts 2 in Seen in the longitudinal direction of the magazine strip 1 have a different overall length.
• the sections of the cord 3 which are exposed between the fastening parts 2 are substantially shorter than the exposed sections of the cord 4.
• the sections 10 of the cord 3 which are in the fastening parts 2 are considerably longer than the sections 11 of the fastening parts 2 Cord 4.
• cords 3 and 4 can also be used instead of the cords 3 and 4.
• the cords, tapes or the like are made of a different material than the fastening parts 2, e.g. of glass fibers or glass fiber-like material, of textile fibers, of metal or metal fibers or the like.
• the cord explained in the above description can also be designed in the form of a thread or a cord.
• cord 3 or 4 can be provided in order to connect the fastening parts to one another.
• the magazine according to the invention is also suitable for all types of washers, nuts, screws made of plastic or the like and of course also for metal screws, which are provided, for example, with a plastic coating on the head.
• the cords, tapes or the like are then cast in this section of the plastic sheathing of the head and run in the same way as in the case of a fastening part 2 provided with a through opening 5, since such a plastic sheathing for receiving the screw head is also a kind of through opening or at least one has a corresponding recess, so that it is generally not possible to continuously pour or press the cord or tape or the like in a straight line.
