ABSTRACT:
In the case of an apparatus for the production of textile pile fabric, and preferably for the production of two bilaterally symmetrical webs of textile pile fabric, comprising a conveying device, able to be driven in steps, for at least one taut support fabric web, with at least one tufting needle bar extending athwart the direction of web conveyance and which bears a plurality of tufting needles placed with a mutual spacing and is able to be moved transversely in relation to the plane of web conveyance, the tufting needdles entraining one respective pile thread and piercing each support fabric web to form a pile thread loop and a loop holding device which is adapted to be reciprocated, is arranged opposite to the tufting needle bar, plunges into the pile thread loops, and preferably places a binding thread therein and in the case of the production of two bilaterally symmetrical textile pile fabrics the conveying device receives two support fabric webs held taut with a distance apart equal to the sum of the individual pile heights and a cutting device is provided at the delivery end of the apparatus in a part between the two support fabric webs for separating the same, it is possible achieve a high pile density and nevertheless a solid design and a straightforward arrangement of the engagement members if each tufting needle bar possesses at least one row of tufting needles extending obliquely in relation to the direction of web conveyance with a plurality of tufting needles arranged obliquely one behind the other and a common engagement member of the loop holding device is associated with each such row of tufting needles, the stroke of such member in the longitudinal direction of the row being at least equal to the length of the associated tufting needle row.
