Abstract
In order to achieve high product quality and process reliability in a process for manufacturing an endless profile strand of soft plastic and/or rubber material fed to a supply storage for a sealing profile, edge protection profile or the like on a motor vehicle, it is provided that the manufacturing process be divided into two process sections which are carried out on two manufacturing lines that can be operated independently of one another.
Claims10
A method for processing a profile strand, comprising:
- feeding the profile strand to an intermediate storage during a first process section;
- removing the profile strand from the intermediate storage during a second process section that is downstream of the first process section;
- and
- then feeding the profile strand to a supply storage;
- wherein the second process section includes cutting one or more defects out of the profile strand, and then one or both of (a) rejoining ends of the profile strand created by cutting out the one or more defects to form one or more joints, or (b) applying an adhesive strip to the profile strand over ends of the profile strand created by cutting out the one or more defects to form the one or more joints, and
- wherein a temperature of the profile strand when the profile strand is removed from the intermediate storage at the beginning of the second process section is at least 50% lower than a temperature of the profile strand at which the profile strand is fed to the intermediate storage at the end of the first process section.

- wherein the second process section includes cutting one or more defects out of the profile strand, and then one or both of (a) rejoining ends of the profile strand created by cutting out the one or more defects to form one or more joints, or (b) applying an adhesive strip to the profile strand over ends of the profile strand created by cutting out the one or more defects to form the one or more joints,
- wherein, in the second process section, one of the ends of the profile strand created by cutting out the one or more defects is a lagging end with respect to a feed direction, and the lagging end is fed in the feed direction to a joining device for subsequent joining one of the ends that is a leading end with respect to the feed direction for producing one of the one or more joints, and
- wherein, in the second process section, an adhesive strip station applies the adhesive strip without interruption over a previously created one of the one or more joints.
