Definitions

• the invention is initially directed to an eyelet for reinforcing the rim around a hole in a track.
• two-part eyelets (EP 0 655 205 B1, US Pat. No. 4,479,287 A, FIGS. 1, 12) which consist of an eyelet part and a disk part are used for this purpose.
• the eyelet has a plate that comes to rest on the show side of the carrier side when riveting, while sitting on a plate tubular neck cuts a hole in the carrier web and is crimped more or less C-shaped with its free end. By flanging the tail of the neck is stiffened. The rigid end piece is supported on the disc part, whereby the carrier web is compressed between the disc part and the plate.
• a riveted two-piece eyelet has insufficient tear resistance.
• the carrier web assumes a labyrinth course between the annular rib and the neck end edge in the interior between the arcuate plate and the C-profile of the neck.
• DE 669 779 A the C-shaped neck flared with its smooth End edge pressed substantially vertically into the carrier web. To avoid bursting the neck end piece when crimping, the neck od without any incision. The like. Be formed. When flanging radial riveting in the folded eyelet edge are impressed by the riveting tool, which should strengthen the crimp end. Due to the corrugated flanging end, the bending stiffness of the neck end piece already produced by the C profile is further increased, so that the folded loop edge can penetrate vertically into the surface of the carrier web.
• the pull-out strength of such one-piece eyelets with a C-shaped flared neck has no higher tear resistance than the two-part eyelet mentioned at the outset.
• the invention has for its object to develop an inexpensive, quickly attachable eyelet specified in the preamble of claim 1 species, which is characterized by a high pull-out strength after Annieten on the carrier web. This is inventively achieved by the measures listed in claim 1, which have the following special significance.
• the flexural rigidity of the beaded edge is reduced in the eyelet according to the invention.
• the bendable neck projections are taken, spread apart with respect to the axis of the riveted eyelet apart and against the circumferential Abutment surface of the plate pressed.
• the tongue-like neck projections thus act as "spreading clamps", which are increasingly pressed against the carrier web with increasing pull-out force.
• a 30% to 75% higher tear resistance is especially true when riveting in flexible or stretchable carrier webs that could not be satisfactorily equipped with a one-piece eyelet so far.
• the neck projections are already co-produced in the production of the eyelet, whereby special operations or processing tools for profiling can be saved.
• the tooth digs into the web material and it can come to a step-like increase along the tooth profile. Apart from the aforementioned Sp Schwarzklemmung it then comes to a positive connection between the tooth and the carrier web. The higher the tensile load applied to the carrier web, the stronger the carrier web digs in front of the antiparallel tooth.
• the invention is further directed to a device for attaching the eyelet according to the invention.
• the known device (US 1,838,973 A), which is, however, intended for two-piece eyelets, jump the pressure ring in the lower tool against the local cutting edge.
• the upper tool has an axially movable central insert with a bore that projects axially relative to the adjacent surfaces of the upper tool.
• the carrier web is pressed into the pressure ring by the central insert of the upper tool; before the central insert hits the cutting edge of the lower tool and thereby cuts the hole in the carrier web.
• the carrier web is in the local two-piece eyelet, which also has the part already mentioned above except the eyelet unsightly attached. It comes to wrinkles in the carrier web.
• the invention is therefore based on the further object of developing a device for the one-piece eyelet mentioned in claim 1, which can be fastened beautiful and tear-resistant to the carrier web.
• This is inventively achieved by the measures mentioned in the characterizing part of claim 9, which have the following special significance.
• the pressure ring in the lower tool in the opposite direction kraftbetasteter counter-pressure ring in the upper tool is assigned. It is recommended, according to claim 10, to provide these two rings with mutually facing oblique and Gegenschrägvid.
• the carrier web is clamped between these two rings, wherein the inclined surfaces provide for an additional smooth pulling of the carrier web. This will maintain a smooth course of the carrier web during subsequent crimping of the one-piece eyelet, resulting in a proper attachment of the eyelet to the carrier web. Clamping minimizes material feed. This has the consequence that the pitches between the eyelets can be maintained exactly and the tolerance deviations are greatly limited even over long tarpaulin lengths.
