Abstract
A weaving machine arrangement includes a heald frame weaving machine and, arranged on both sides of the latter, two sets of accessory equipment. The warp thread set of the heald frame weaving machine is divided into a first set and second and third warp thread sets. The second and third warp thread sets are used in order to form extended turning-fold areas in the tubular-woven material. The accessory equipment forms patterns for the terminating positions of the weft threads in these areas, strong seaming functions are obtained in the tubular-woven material. Cut-off thread ends are anchored by heat action. The degree of automation is increased in relation to conventional manufacturing by virtue of the fact that the seaming function can be carried out in the heald frame weaving machine itself.
