Abstract
Weaving machine, method and selvedge forming apparatus for introducing into a shed an end (30A) of a weft thread (30) which has been inserted into a shed, the selvedge forming apparatus (4, 5, 6) being provided with a device (20) for introducing the end of the inserted weft thread into a subsequent shed, wherein the selvedge forming apparatus (4, 5, 6) comprises a blowing device (50) having at least one blowing opening (51) which, in use, can be positioned at the level of the plane of a selvedge (16, 17) of the woven fabric (2, 3), with the blowing device (50), in use, blowing essentially toward the beat-up line (36).
Claims21
Selvedge forming apparatus (4, 5, 6) for a weaving machine, the weaving machine comprising
- a device (7) for beating-up the inserted weft threads (30) while moving to a beat-up line (36), the selvedge forming apparatus comprising
- a device (20) for introducing an end (30A) of a weft thread (30), which has been inserted into a shed, into a subsequently formed shed,
- wherein in that
- the selvedge forming apparatus (4, 5, 6) comprises a blowing device (50, 61) arrangeable close to the plane of a selvedge (16,17) of the fabric (2, 3) being woven for blowing an air-stream onto the introduced end (30A) of the weft thread (30) which air-stream is essentially directed towards the beat-up line (36).
Weaving machine comprising
- a device for forming sheds of warp threads (14),
- a device for inserting weft threads into the sheds,
- a device (7) for beating up the inserted weft threads at a beat-up line (36),
- and a selvedge forming apparatus (4, 5, 6) comprising a device (20) for introducing an end (30A) of an inserted weft thread (30) into a subsequently formed shed,
- wherein the selvedge forming apparatus (4, 5, 6) comprises a blowing device (50, 61) arranged close to the plane of a selvedge (16, 17) being formed for blowing an air-stream onto the end (30A) of the weft thread (30) being introduced into the shed which air-stream is essentially directed towards the beat-up line (36).
Method for forming a selvedge (16,17) at a fabric (2, 3) during weaving
- comprising the steps of
- inserting a weft thread (30) into a shed formed of warp threads (14), beating-up the inserted weft thread by a device moving to a beat-up line (36),
- introducing an end (30A) of the inserted weft thread (30) into a subsequently formed shed,
- inserting the next weft thread (30B) into that subsequently formed shed, and beating-up this weft thread (30B) together with the end (30A) of the previously inserted weft thread (30) at the beat-up line (36),
- wherein, before beating up the end (30A) of the weft thread (30) an air-stream is blown onto said end (30A) of the weft thread (30) introduced into the shed, which air-stream is essentially directed towards the beat-up line (36).
