<p>PCT No. PCT/EP81/00174 Sec. 371 Date Jul. 1, 1982 Sec. 102(e) Date Jul. 1, 1982 PCT Filed Oct. 31, 1981 PCT Pub. No. WO82/01727 PCT Pub. Date May 27, 1982.The present invention relates to a gripper apparatus on a ring spinning or ring twisting machine for gripping empty and/or wound bobbin tubes using pegs mounted on a support beam extending along the machine and inserted into the interior space of the bobbin tubes, the bobbin tubes being gripped by pressing each bobbin tube and the peg inserted into it against each other. The pressing generally is effected using compressed air. According to the invention at each peg a cylindrical extension made of elastically bendable material is provided, which extension extends from the front end of the peg towards the tip thereof. This arrangement yields the advantage that in case of faulty positioning of bobbins, tubes a head-on collision of the peg front end on the upper bobbin tube rim, with accordingly grave consequences, such as e.g. damage to the support beam or blowout of the compressed air, no longer can occur.</p> |
