Abstract
In an apparatus for joining textile threads with the aid of compressed air, there is provided a device for checking the tearing strength of the joint zone of the threads before their extraction from the apparatus. The device comprises at least one mobile member arranged to act on the loop formed by the joined threads with a predetermined traction force at an intermediate point between the points at which the threads are locked at the apparatus inlet. Control means are provided which are operated so that they travel through a predetermined outward and return stroke and act on said mobile member by way of a yieldable coupling which is set to yield when the predetermined traction force is exceeded.
