Draw-in or push-out tube for a hollow-spindle stop independent of stroke

摘要

The modification of the hitherto conventional draw-in or push-out tubes to tubes with three longitudinal slots according to Claim 1 is the only possibility of attaching stops in the inner area of the tubes independently of stroke. Since work is carried out very frequently with a stop on the lathe, it appears necessary to me to obtain a patent before launching the tube on the market in order to protect this invention in the main claim and sub-claim.
