## Abstract

Controlled compressed-air splicing device for textile threads with a controlled compressed-air metering valve supplied from a compressed-air supply device, including an automatic quality control device for ensuring the quality of spliced joints formed by the splicing device.

## Claims

### Claim 1

Controlled compressed-air splicing device for textile threads with a controlled compressed-air metering valve supplied from a compressed-air supply device, comprising an automatic quality control device for ensuring the quality of spliced joints formed by the splicing device, said quality control device comprising a pressure monitor having an adjusting device for at least one of a minimum pressure, on the one hand, and tolerance limits of a pressure range, on the other hand, said pressure monitor communicating with the compressed-air supply device and being operatively connected to at least one device of a locking device for locking the compressed-air splicing device and an alarm device for signaling when the pressure deviates from a given pressure.
