Abstract: The invention relates to a method for inserting weft yarn material, comprising an insertion system in a loom. According to the invention, for every insertion the insertion system (A) is supplied with a substantial part of the weft yarn required for the insertion in a loose and substantially tension-free manner so as to be intermittently pulled off. A tubular package of adjacent windings is produced from the weft yarn material on an inner mechanical support (S) by way of an at least substantially continuous winding process and is conveyed forward in withdrawal direction. For an insertion, a number of windings that corresponds at least approximately to the weft yarn section intended to be inserted is detached or set free from the support while maintaining its tubular configuration without yarn tension. The weft yarn material is withdrawn directly inwardly from the frontmost winding and then further along the tube axis (X).

Abstract: A feeding device for a mechanical weaving machine, including a winding element which can be driven in a rotating manner, a stationary storage, and at least one stop element. The stop element can be axially and radially moved in relation to the storage body, between an unwinding position releasing thread yarn and a stop position wherein the stop element is applied to the foremost winding and which ends the weft insertion. A yarn clamp is arranged downstream from the stop element, which initiates the respective weft insertion, and which can be switched between a passive position and a clamping position. The storage body has a small diameter, and the stop element is moved axially to the stop position solely by the windings due to a transport motion of the windings on the storage body.

Abstract: The invention relates to a feeding device (F) for a mechanical weaving machine (T), comprising a winding element (W) which can be driven in a rotating manner, a stationary storage body (K), at least one stop element (S) which can be essentially axially and radially moved in relation to the storage body, between an unwinding position releasing thread yarn (Y) and a stop position which is applied to the foremost winding and which ends the weft insertion, in addition to a yarn clamp (C) which is arranged upstream from the stop element (S), which introduces the respective weft insertion, and which can be switched between a passive position an a clamping position. The inventive feeding device is characterised by a storage body (K) having a small diameter, and by a stop element (S) which can be exclusively moved axially to the stop position by the windings (YT) due to a transport motion (B) of the windings on the storage body (K).
