Abstract
The present invention concerns an apparatus for winding threads or yarns and similar strands, in which a friction drive roll and a bobbin support roll are provided. The latter is supported only at one end, and the other end is free, in such manner that easy operation is possible. In arrangements of such type any deviation, however small, of the two rolls from their correct, parallel position, is to be avoided if correctly built bobbin packages are to be produced in the winding process. This is achieved according to the invention in that a coupling means, coupled or connected with the bobbin support roll, which moves during the winding process, brings about a forcible parallel alignment of the two rolls.
Claims12
A winding apparatus for threads or the like, comprising:
- a bobbin support roll upon which there is formed at least one bobbin package;
- a friction drive roll cooperating with said bobbin support roll;
- each of said rolls having an axis of rotation;
- said rolls being arranged substantially mutually parallel to one another and with their axes of rotation located in superimposed fashion in a substantially vertical plane;
- one of said rolls being subjected to displacement movements caused by an increase in the size of the bobbin packages formed upon the bobbin support roll;
- means for mounting and guiding said one roll to enable said one roll to carry out said displacement movements in a direction substantially parallel to said vertical plane;
- means providing a pivot axis for enabling pivotal movement of one of the rolls in a direction substantially parallel to said vertical plane about said pivot axis;
- said mounting means including bearing means located at one end of said roll subjected to said displacement movements for supporting said roll;
- and
- coupling means responsive to the displacement movements of said one roll for causing pivotal movements of said one pivotable roll about said pivot axis in the sense of bringing about an automatic parallelization of said rolls with respect to one another.
