Oct. 15, 1929. s. c. 1.. GINESTE LACHAZE 1,731,426 THREAD OR WIRELDRIVING MEANS FOR CORE COVERING MACHINES AND THE LIKE Filed April 2, 192a rzfan/ Czar/es Ze ah/ lw'nesfe zac-go" Patented Oct. 15, 1929 UNITED STATES PATENT OFFICE GASTON CHARLES LEON GINESTE LACHAZE, F CALUIRE, FRANCE THREAD 0R WIRE DRIVING MEANS FOR CORE-COVERING MACHINES AND THE LIKE Application filed April 2, 1928, Serial No. 266,858, and in France April 11, 1927.
This invention relates to improvements in thread or Wire driving means for covering machines and the like such as, for instance, electrical wire covering machines, in which a copper wire is covered with silk or cotton, or guimperie machines, in which a cotton thread is covered with a thin metallic strip.
It is essential, in such machines, to provide a constant speed of the thread or wire to be covered, in order to obtain a regular covering of the same. When this thread or wire is driven by the reel on which it is wound, the speed of this reel must be corrected from time to time since its diameter increases, which results in an increase in the speed of the thread or Wire for the same angular speed of the reel.
According to this invention, the angular speed of the reel is automatically varied and a constant linear speed of the thread or wire is obtained, by driving the reel by means of a belt or the like which acts on the periphery of the cylinder formed by the covered thread or wire already wound on said reel.
In the annexed drawings:
Fig. 1 is a diagrammatic elevation of the essential parts of a thread or wire covering machine.
Fig. 2 is a section on line 2-2, Fig. 1.
The core 1 (thread or wire) passes through a hollow spindle 2 which supports the cop or cops containing the threads, strips or the like which are to be helically wound on core 1 to cover the same. The covered core passes over idlers 3, 1 and 5 and then through the guide 6 from which it is led to and wound on the reel 7 whereon it forms a cylinder 8.
This reel 7 is driven from a driving shaft 9 provided with a step pulley 10, by means of 4.0 an endless belt 11 which is passed around the cylinder 8 itself. An idler 12 is provided for tensio'ning the belt. 1
It is apparent that the linear speed of the covered core 1 is constant, since it is equal to the speed of the driving belt 11 itself.
It may be necessary to protect delicate work or to increase the adhesion of the belt. This is easily obtained by means of an endless band 13, the width of which is equal to the width of around the reel 7 and tensioned by means of a roller 14. The core 1 is wound beneath band 13, and the belt 11, on the contrary, runs on the band and thus does not contact with the work;
It is to be understood that the term belt embodies any endless supple means, such as belt for said reel, said belt acting on the periphery of the cylinder formed by the covered core already wound on said reel; tensioning means for said belt; a guide for said covered core, said guide being located in such a way that said core comes into contact with said cylinder in the angular part thereof on which said belt does not contact; and guiding means to prevent said core from interfering with said belt. I
2. In thread or wire covering machines and the like, driving means for the covered core, as claimed in claim 1, said means comprising an endless band interposed between the cylin der formed by the covered core on the reel and the driving belt acting thereon.
In testimony whereof I affix my signature.
