US 2006/0144458 A1 · Method for producing a textile in plain weave and gauze weave and weaving machine for carrying out said method

Abstract

The aim of the invention is to obtain a plain weave and gauze weave in a textile that is to be produced, in one weaving cycle, thus economising in terms of expensive shed-forming elements. To achieve this, according to the invention, the plain weave (16) and gauze weave (15) are formed simultaneously in the textile (9) in one weaving cycle. To form the plain weave (16), the adjacent warp threads (1L,2L) that are used to form the upper shed and lower shed are alternately lifted by the same drop wire/needle shank (4) from the lower shed position into the upper shed position and lowered from the upper shed position into the lower shed position. To form the gauze weave (15), only the warp threads (2D) that form the upper shed are raised in a known manner by the drop wire/needle shank (4) from the lower shed position into the upper shed position and lowered from the upper shed position into the lower shed position.

Method for producing a fabric in plain weave and leno weave, according to which warp threads (1L, 2L;

1D, 2D) are drawn in a first blade and needle shaft (3) which can be displaced back and forth in an oscillating manner transversely relative to the path of the warp threads (1L, 2L;
1D, 2D) in order to form a lower shed, and warp threads (1L, 2L;
1D, 2D) are drawn in a second blade and needle shaft (4) which moves upwards and downwards in an oscillating manner in order to form an upper shed, characterised in that the plain weaves (16) and the leno weaves (15) are simultaneously formed in the fabric (9) during a weaving cycle.

Loom for producing a fabric which has both plain weaves (16) comprising weft threads (34) and warp threads (1L, 2L) and leno weaves (15) comprising weft threads (34) and warp threads (1D, 2D), the loom comprising:

a slay (6) which carries a weaving reed (5) and which carries out an oscillating pivoting movement about the longitudinal centre axis (28a) of the slay shaft (28),
a first blade and needle shaft (3) which is connected to a drive (41) which brings about an oscillating back and forth linear movement of the blade and needle shaft (3) transversely relative to the weaving plane (35) and
a second blade and needle shaft (4) which is adjacent to the first blade and needle shaft (3) and which is connected in a rotationally secure manner by suitable means (37) to a shaft (36) which is arranged remote from the slay shaft (28) of the loom and which carries out an oscillating forward and backward rotational movement about the centre axis (36a) thereof,
characterised in that, in order to produce the leno weaves (15), a needle blade (11) having a thread guiding eyelet (11a) is connected in each case between two of the rod blades (10) which are arrested at an upper shaft connection (30) and a lower shaft connection (29) of the first and second blade and needle shaft (3;4), and, in order to form plain weaves (16), a plurality of rod blades (10) are arranged beside each other in the first blade and needle shaft (3), with which rod blades (10) there is associated a shoulder blade (12), having a shoulder (13a, 14a) which is arranged at one side or at both sides for supporting at least one warp thread (1L, 2L), in the second blade and needle shaft (4) of either each even-numbered or each odd-numbered rod blade (10) of the first blade and needle shaft (3).

a slay (6) which carries a weaving reed (5) and which carries out an oscillating pivoting movement about the longitudinal centre axis (28a) of the slay shaft (28),
a first blade and needle shaft (3) which is connected to a drive (41) which brings about an oscillating back and forth linear movement of the blade and needle shaft (3) transversely relative to the weaving plane (35) and
a second blade and needle shaft (4) which is adjacent to the first blade and needle shaft (3) and which is connected in a rotationally secure manner by suitable means (37) to a shaft (36) which is arranged remote from the slay shaft (28) of the loom and which carries out an oscillating forward and backward rotational movement about the centre axis (36a) thereof,
a needle blade (11) having a thread guiding eyelet (11a) being connected in each case between two of the rod blades (10) which are arrested at an upper shaft connection (30) and a lower shaft connection (29) of the first and second blade and needle shaft (3;4) in order to form the leno weaves (15), and, in order to form plain weaves (16), a plurality of rod blades (10) being arranged beside each other in the first blade and needle shaft (3), with which rod blades (10) there is associated a shoulder blade (12), having a shoulder (13a, 14a) which is arranged at one side or at both sides for supporting at least one warp thread (1L, 2L), in the second blade and needle shaft (4) of either each even-numbered or each odd-numbered rod blade (10) of the first blade and needle shaft (3), characterised in that, in order to form the plain weaves (16), each of the even-numbered or each of the odd-numbered rod blades (10) of the blade and needle shaft (3) is also a shoulder blade (12) which has at least a shoulder at one side counter to the direction (42) of the supplied warp threads (1L, 2L;
1D, 2D) having a downwardly open trough-like recess in the shoulder (13a;14a) for retaining the warp threads (1L) or the warp threads (2L).
