Description

[Detailed description of the invention] This invention is a two-press roller type beaming machine or gluing machine that uses two press rolls.
The present invention relates to the press roller of a machine (hereinafter simply referred to as a beaming machine) that winds up a thread-like material to create a beam.

For example, in a beaming machine for a Sulzer loom that uses two conventional press rollers, when the press roller presses the yarn surface of the beam being wound up, the part pressed by two press rollers and the part pressed by one press roller. The part that is pressed is generated. In this case, among the two end surfaces of the two press rollers, the open end surfaces opposite to the end surfaces that are in contact with the opposing inner surfaces of the beam flange are perpendicular to their axes. Part to be pressed and 1
The boundary line with the part to be pressed by the book is a direct line along the thread, which is the rotation locus drawn on the winding beam surface by the circumferential edge of the open end surface, and its position is always constant. , so-called steps will be added to the boundary line. As a result, when the beam is set on a loom and weaved, the yarns near the boundary line overlap, resulting in so-called beam biting, which may cause yarn breakage during weaving or the formation of weaving defects such as loose yarns. Cause.

The purpose of the present invention is to solve the above-mentioned drawbacks. Specifically, the present invention has a beam length longer than the half-width length of the beaming machine, etc. that is pressed into contact, but shorter than the full width length, and one of its both end faces. In two press rollers whose end surfaces are in contact with the opposing inner surfaces of the beam flange and whose other end surfaces are open end surfaces, each open end surface of the press rollers is made obliquely perpendicular to the axis of the press roller. This makes it possible to eliminate the above drawbacks.

The configuration of the present invention will be described in detail below based on one embodiment.

Figure 1 is a perspective view of the beam with conventional press rollers 1 and 2 as shown in Figure 2 attached and winding up the yarn Y, Figure 3 is its side view, and Figure 4 is the beam being rolled up. A front view of the beam thread is shown. As shown in Fig. 4, the winding beam yarn is formed by two parts, W ₁ and W ₂ , which are pressed by only one press roller 1 or 2, and by two rollers, press rollers 1 and 2. It consists of pressurized parts W ₁ and ₂ ,
Among the end faces of the press roller 1 or 2, the open end face 1 that is not in contact with the inner surface of the beam flange 3 or 4
Loci L ₁ , L ₂ drawn by the rotation of a or 2a
is the boundary line. In this case, the open end surface 1
Since a and 2a are formed perpendicularly to the respective axes of press rollers 1 and 2 as shown in Fig. 2, L ₁ and L ₂ are straight lines along the yarn Y. 〓〓〓
Moreover, its position is always constant. Therefore, at the boundary line, the threads Y have irregular tensions, overlap and become entangled.

On the other hand, when the yarn Y is wound up by a beaming machine equipped with press rollers 5 and 6 according to the present invention shown in FIG. 6, the open ends 5a and 6a of the press rollers 5 and 6 are As shown in FIG. 7, it is formed obliquely to the axes of the press rollers 5 and 6, so that in the winding beam yarn, as shown in the front view of FIG. or 6, the portions W ₅ and W ₆ that are pressed by only one roller, and the press rollers 5 and 6.
The boundary lines with the portions W ₅ and ₆ pressed by the two rollers become meandering lines L ₅ and L ₆ . The boundary line is the so-called diagonal open end surface 5a of the press rollers 5 and 6.
This is because the locus is drawn by the rotation of the peripheral edge of 6a and 6a. Therefore, near the boundary line,
The threads Y do not overlap or become tangled due to uneven tension.

As described above, when the press rollers 5 and 6 according to the present invention are used to perform beam winding of yarn, problems often occur when conventionally two press rollers are used to perform pressure winding. In addition, there is no overlapping or entanglement of threads due to tension irregularities near the boundary line, which is the locus drawn by the open end surface of the press roller, and there is no possibility of thread breakage during weaving or loose threads caused by the biting of the beam. This is an extremely useful device, as it reduces weaving defects and improves the operating efficiency of the loom and the quality of the woven fabric.
