ABSTRACT:
Each chuck of the capstan is peripherally integral with a rim made from a relatively elastic material which defines, facing each indexing bore for the formation of a shock absorber/stop member, an orifice whose outlet cross-section is substantially the same as the inlet cross-section of the said bore and, in the vicinity of the indexing pin a cross-section which, at least in the direction of travel of the chuck, is larger than the cross-section of the end fitting of the said pin, each orifice having a sloping wall which converges towards the central area of the said chuck.
The improvements forming the object of the invention are applicable to capstan tool holders for punching machines.
