Abstract

A feeding device for effecting a longitudinally directed relative movement between a stem and the device proper comprises at least one feeding unit in the form of an endless band or band-like element which is drivable by means of at least one rotatable wheel. The endless element is composed of a large number of hingedly interconnected chain-forming links (11, 12) which are movable along the outer side or the periphery of an elongate guide bar and which, by bearing against said bar (10), are adapted to transfer substantially uniformly distributed bearing pressures to the stem substantially throughout the length of said bar.
