Document Type and Number:
Japanese Patent JPH08218249
Kind Code:
A
Abstract:

PURPOSE: To simplify preparation operation for forming laminated yarn groups and operation for bonding laminated yarn groups with yarn in the thickness direction and to enable three-dimensional yarn texture having a high yarn arrangement density.

CONSTITUTION: Laminated yarn groups 3 at least bi-axially oriented are formed by arranging yarn on a frame 2 provided with the pins 13 at fixed pitches so as to be folded by pins 13. In a state of the laminated yarn groups 3 held on the frame 2, yarn inserting needles 28 in the thickness direction arranged in a row are inserted into the laminated yarn groups 3, yarn (z) in the thickness direction is inserted into the laminated yarn groups 3 in a folded state and removal preventing yarn P is inserted into the loop. The laminated yarn groups 3 are pressed near the line of the inserting needles 28 by a press plate 39 and press blocks 44 and 45 and the inserting needles 28 are returned to the former place in the state and the laminated yarn groups 3 are fastened to prevent removal of the yarn (z) in the thickness direction. After the yarn (z) in the thickness direction is inserted into a fixed insertion zone, the laminated yarn groups 3 are removed from the frame 2.
