Buffer for looms TBUb0ZU

The invention relates to a buffer for looms, which is used as a buffer head for hydraulic ^. Buffer and can be used as an end stop can.

The buffer according to the invention has a suspension slot in a known manner for shock absorption. The well-known buffers of this type However, especially when used as a buffer head for hydraulic Rifle catching buffer has the disadvantage of an often excessive abrasion. The object of the invention was to reduce this abrasion or to eliminate it, ie. increase the lifespan of the buffer.

Hydraulic landing buffers are known to be like that. arranged, that the piston of the buffer is perpendicular to that in its outermost Position inclined baton. Due to this inclined position of the buffer piston, the buffer head moves during Push in the piston from its starting position A (Figure 1) its end position E by the amount G downwards. The baton moves due to the straight guidance that is present in almost all looms not like the buffer piston downwards but on a horizontal one Route S (Figure 1). Every time the hydraulic is pushed in Buffer, therefore, the baton slides onto the buffer head by the distance G, which is about 2-3 mra. That slip creates one severe abrasion on the buffer head of the hydraulic buffer.

The object of the invention, it is ^ this Abrieb.der the life of the buffer heads affected greatly reduce _e object is achieved by a U-shaped bracket of elastic material which not only absorbs in the impact direction but also in longitudinal direction of the baton is movable "When buffer According to the invention, there is no longer any relative movement between the often not very smooth baton and the buffer head. In the case of the new buffer, the bracket slides on the rest of the buffer part, with significantly less abrasion, since long-lasting lubrication is possible at this point and because the smooth plastic parts cause less abrasion even when running dry ^

especially if plastics of different hardness are used for the bracket and the rest of the buffer part. A made of plywood * If you look closely, the baton is not smooth but works through the transverse layers of veneer like a fine file, which accordingly causes severe abrasion.

Look the Pig. 1-5 the invention will be explained in more detail. The buffer head consists of the U-shaped bracket 1, which is separated from the rest of the buffer body by a U-shaped suspension slot 2, 3. The U-shape of the yoke enables the front part of the bracket, a movement in the longitudinal direction of the baton ^ The buffer body is by means of the chip 5 and the nut 6 / W of the sub legscheibe 8, attached to the screw ¹ J. Between the plate 5 and the buffer part 4 there is a second, narrow Pederungsschlitz 9 arranged around the relatively massive part 4 and an additional one

To give compliance.

While in the buffer according to FIG. 2 the bracket and the rest of the buffer body consist of one piece, the buffer according to FIG. 3 consists of two parts, namely the part 1 containing the bracket and the part ^{4A with the recess 5 · D e} -r inner part of the buffer body can also be made of leather as shown in FIG. This version is particularly suitable for end stops where particularly high damping without springback is required.

In FIG. 5, a buffer is shown which is connected to the fastening screw by a snap connection in a manner that is particularly easy to assemble. The fastening screw has a wrench attachment, for example a hexagon head 10, a bolt 11 with an edge 12 which, when the buffer is pressed on, engages in a corresponding recess in the buffer body. The slot 13 serves as an anti-twist _{device Ϋ}
