The invention relates to a button for fastening or closing webs of material, in particular textiles, with one head and one on one side central arranged fastening device.

It is the object of the invention to create a button which enables webs of material to be buttoned together and this very easily without the use of a needle and Thread can be attached. Such a button should be used in the industrial production of items of clothing, for example and can also be used easily and simply when replacing the previously common buttons.

To solve this problem, a button is the one at the beginning named type according to the invention designed such that the fastening device is arranged on the head Comprises a spacer element and a tip provided thereon made of deformable material, which is supported by a web of material pluggable and then on a disk-shaped fastening element can be fastened by deformation.

A button according to the invention is very simply constructed and can easily be attached to material webs by its tip is pushed through the respective material web, for example through a textile fabric, suspect to "damage the material. The spacer element is brought to one side of the material web so that the Head to this has a certain distance. Then the fastener is on the. other side of the material web attached to the tip inserted through it.

An embodiment of a button according to the invention is described below with reference to the figures. Show it: Fig. 1 is a perspective view of two components

of the button before attachment and FIG. 2 shows a cross section of the attached to a piece of textile Button.

The button has a disc-shaped main part or head 2, on one side of which a spacer element 4 is arranged centrally is. This carries a narrow connecting tip 6 made of plastic material protruding from it. The spacer 4 forms a centrally arranged projection on which the connecting tip 6 stands. The face of the protrusion 4 has a raised circumferential edge 8 which surrounds the connecting tip 6 and which is beveled.

The connecting tip 6 can be pushed through a fabric or a material web, so that the beveled Circumferential edge 8 is brought into contact with one side of the fabric and the head 2 a corresponding one Distance to this side. A round disc 10 with a central through opening 12, which is on a Side is provided with an extension, is then in the direction of arrow 14 in contact with the other side of the Tissue brought so that the connecting tip 6 through the

Opening 12 is passed through. The mouth tip 6 is then compressed in the extension 12, so that the arrangement shown in Fig. 2 in cross section results.

If the orifice tip 6 is made of a thermoplastic If there is material, the upsetting process is caused by the action of heat and pressure. In other species of plastic material can also be a cold upsetting or upsetting can be carried out by the action of ultrasound. The end of the connecting tip 6 is preferred slightly beveled so that it can be passed through the fibers of a fabric without damage. the concave surface of the spacer 4 between the beveled Edge 8 and the connecting tip 6 serve primarily to form a space for tissue material, which could form folds through the introduction of the connecting tip, furthermore the edge 8 enables a Pressure on the fabric. This is not damaged because the edge 8 is beveled. The extension 12 in the disk 10 is preferably dimensioned so that the connecting tip 6 is practically complete when upsetting is absorbed in it. The diameter of the spacer element 4 is of course dimensioned so that it fits into a buttonhole.

The invention is based on the exemplary embodiment described above not restricted, but rather all of the features described and claimed can be used individually or in any Combination be essential to the invention.
