Abstract

The invention relates to a novel process for producing twisted prepared lines, in which process at least two individual lines after their preparation are then twisted in a twisting device with clamping between two holders between which a twisting segment is formed and of which one can be moved along this twisting segment, by turning at least one holder, and to a novel device for executing the process.

Claims

1. A device for producing twisted prepared electrical lines, with a carriage guide, for a carriage, provided on a device frame, having a first holder located on said carriage, a second holder provided in one end of said carriage guide on said device frame, a twisting segment disposed between said first holder and said second holder, said first holder being driven to rotate around an axis of said twisting segment by a drive, comprising:

control means for controlling said first and second holders, said drive and a carriage drive such that before a start of each twisting process, individual lines are tensioned so that an entire length of each of said individual lines is between said first holder and said second holder on said twisting segment and then said individual lines are twisted, while corresponding braking of said carriage to maintain a predetermined tension, by turning said first holder provided on said carriage.

2. A device as claimed in claim 1, wherein said first holder provided on said frame comprises first holding tongs.

3. A device as claimed in claim 1, further comprising transfer means for simultaneous transfer of at least two of said prepared individual lines from a preparation device to one of a twisting device and said second holder,

said transfer means having at least second holding tongs movable in a transfer movement between first position on said preparation device and at least one second position where said second holding tongs lie adjacent said first holding tongs.

4. A device as claimed in claim 3, wherein second holding tongs can be moved for one stroke transversely to said transfer movement.

5. A device as claimed in claim 1, further comprising a capping station for pushing one of a housing and a socket onto ends of said individual lines, said individual lines being held preferably in one said second holder and are provided with electrical contacts.

6. A device as claimed in claim 5, wherein said capping station is provided on said device for producing a twisted pair.

7. A device as claimed in claim 5, wherein said capping station is a component of a capping device, and wherein a transfer means is provided between said twisting device and said capping station, wherein said individual lines with ends to be capped are moved from said twisting device to said capping station.

8. A device as claimed in claim 1, wherein two of said twisting devices are provided for one preparation device, and wherein between said preparation device and said two twisting devices is disposed a transfer means for feeding said prepared individual lines to said two twisting devices.

9. A device as claimed in claim 1, further comprising an intermediate tray for holding said twisted segment, wherein said intermediate tray can be opened under control of control means.
