Abstract
A process for producing a stick of adhesive, having a rotatable base part with rotary spindle, which spindle is engaged in a holding element for the stick material (plunger, small basket, anchoring disc), which holding element is fitted into a sleeve surrounding the stick material. The rotary spindle, provides controlling movement of the stick-shaped adhesive material either up or down. The sleeve (2) together with the plunger (1) is formed in a one-part injection molding which is joined, via predetermined breaking points (3), to the sleeve wall. For the assembly, the base part, with rotary spindle is pushed through a centered recess in the plunger until the lower periphery of the sleeve comes to rest against the upper part of the base part. The adhesive stick material is then poured into the unit thus formed (sleeve, plunger and base part with rotary spindle), and, after the filling operation is complete, the rotatable base part is actuated and, as a result, the plunger is lifted into the intended end position (10), with tearing off of the predetermined breaking points. The structural arrangement for carrying out the process, consists of: a) a rotatable base part (7), a rotary element (7B) and a rotary spindle (7A), the base part having two support plates (9A, 9B), and b) a one-part injection molding, comprising a sleeve part (2) which is open at both ends and a plunger (1) with predetermined breaking points (3).
