Definitions
- the invention relates to a method for producing an adhesive fastener part with a multiplicity of interlocking means formed with a carrier on one of its two sides, an adhesive agent being applied to the opposite side and with a silicone-containing separating layer at least partially on the side of the carrier with the interlocking means is applied.
- the adhesive fastener parts produced in this way can be wound up in the form of tape or flat material to form roll containers, the respective adhesive being usually provided in the form of a rubber-based hot-melt adhesive with a cover paper in order to prevent the adhesive from being firmly bonded to the underlying interlocking means.
- the adhesive medium later serves to fix the fastener part depending on its intended use on a floor or on a diaper material, provided that the fastener part is used to fasten a carpet material or as a fastener part for a baby diaper or the like.
- the silicone-containing separating layer is introduced in essentially the same portions, distributed in the respective recess on the front side of the hooking head, a uniform opening and unwinding behavior is also achieved, so that there is a uniform force distribution of the adhesive forces between the adhesive layer and the hook material. It is also surprising for a person skilled in the art that he not only achieves a uniform opening behavior with the measures shown, but also that with the manufacturing method according to the invention one arrives at an adhesive closure part with which one can carry out multiple winding and unwinding processes , with the rewinding process again resulting in a corresponding, but not permanent, adhesion of hooking means with the adhesive material above.
- the interlocking means consist of stems having thickened ends, for the manufacture of which a plastic material is fed to a gap between a printing tool and a molding tool and these tools are driven such that the carrier is formed in the gap and conveyed in a transport direction is used in which a continuous hollow screen is used as the shaping element on the molding tool and in which the interlocking means are formed in that the plastic material in the hollow spaces of the screen at least partially hardens.
- the manufacturing process for the carrier is known from DE 198 28 856 C1. As a result, the starting material to be coated can be produced very quickly on an industrial scale in the form of the tape-like or sheet-like fastener parts.
- thermoplastic is used as the plastic material.
- adhesive closure part is rolled up into transportable containers so that the adhesive is in direct contact with the hooking means underneath. It has been shown that the speeds for the coating process can be between 10 and 100 m / min in the transport direction of the adhesive fastener part. This significantly increases the production speed for the adhesive fastener part according to the invention, these production speeds would not be achievable if the adhesive were to be provided with a masking tape or paper in the usual way.
- the adhesive fastener part 23 being provided with an adhesive layer 25 on its rear side.
- the adhesive agent in question is preferably a rubber-based adhesive.
- the adhesive agent itself is applied to the back of the adhesive fastener part 23 in the usual and therefore not described in detail.
- the thickened ends 19 on the stems 17 form the actual hooking means 27, which are to be provided with the release coating.
- the thickened ends 19 themselves can be calendered for final shaping as the interlocking head of the interlocking means 27 (not shown in more detail).
- the thickened head ends 19 of the interlocking means 27 have a recess due to production technology reasons, this recess can be filled with the silicone-containing separating layer means 29.
- the locations on the upper side of the carrier 11 that are kept free of the hooking means 27 are silicone-coated (not shown). It is crucial, however, that the point which, in the wound-up state of the adhesive closure part 23, is arranged adjacent to the adhesive substance 25, has the silicone cover in order to prevent the adhesive from sticking to the underlying strip material.
- the blank sample of the adhesive 25 contains 2.9 to 3.2 atom% silicon.
