Abstract

In the outer sleeve there runs a threaded spindle which is mounted in a bearing sleeve (5) and on which a piston (30) is movable up and down. The outer sleeve (1) is in relation to its inner diameter Ad considerably longer than with known glue sticks. The ratio of the inner diameter Ad of the outer sleeve (1) to the length AL of the part of the outer sleeve which serves for receiving a rod-like adhesive mass (10) here lies in the region of 1:6 to 1:15. This however according to the invention demands that the threaded spindle is configured such that it simultaneously serves as a conveyor worm. Thanks to the special configuration of the piston (30) is spite of the great length of the threaded spindle there is achieved a bending-breakage stabilization.
