Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction of a cylinder half-lap for a comber.

As shown in Fig. 1, the conventional cylinder half-lap for combing has grooves 2 in the cylinder half-lap body 1.
are formed in the radial direction of the cylinder, and a small groove 3 is formed in an oblique direction, a needle plate 5 with a needle head 4 is laminated, and the needle plate 5 is inserted and fixed into a band-shaped metal plate 6 and a dovetail groove 7 provided on the side surface of the needle plate. The needle row ribbons 8 formed by the above-mentioned method were inserted into the grooves 2 and arranged in rows. Note that the protrusion 9 provided on the side surface of the throat plate 5 is engaged with the small groove 3.

In the above-mentioned combed cylinder half-lap,
The degree of fitting between the groove 2 and the needle row ribbon 8 is important; there must be no gap and the needle row ribbon 8 must be easily inserted. However, when the fibers are subjected to the combing action by the needle head 4, the component force F1 acts in the direction of pulling the needle row ribbon 8 out of the groove 2, and when used for a long time, the gap between the groove 2 and the needle row ribbon 8 becomes larger. .

Furthermore, the needle row ribbon 8 is formed by inserting and fixing a band-shaped metal plate 6 to the throat plate 5, but since the position where the metal plate 6 is inserted and fixed is on the side of the throat plate,
The holding area of the groove 2 to the needle row ribbon 8 is small, which exacerbates the above-mentioned drawbacks.

The cylinder half-lap for combing according to the present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the drawings.

Embodiment FIG. 2 is a sectional view of essential parts showing an embodiment of the combed cylinder half-lap of the present invention.

The cylinder half-lap body 1 has grooves 10 having a generally inverted T-shaped cross section in the axial direction at equal intervals around the cylinder circumference.
to be drilled.

A needle base portion 12 having a needle head 11 having a working angle α in the cylinder rotation direction on the upper part, and a needle insertion portion 13 having a substantially inverted T shape.
Accordingly, a hole 14 is provided in the needle base 12, and a slit 15 communicating with the hole 14 is provided in the needle insertion portion 13 to form a throat plate 16.

The needle heads 11 of the throat plates 16 adjacent to each other in the direction of the cylinder axis are stacked so that the needle heads 11 of the throat plates are arranged in a staggered manner and are alternately shifted in the cylinder rotation direction, and the slits 15 of the throat plates are made of metal or synthetic material. The continuous body 17 made of resin or the like is fitted and fixed, and the throat plate laminate 18 is attached to the third
Form as shown.

The throat plate laminate 18 is inserted and arranged in the groove 10 of the cylinder half-lap main body to constitute the cylinder half-lap for a comb according to the present invention.

Incidentally, if the concave portion 19 is provided so that the upper part of the side surface of the needle base 12 is in contact with the needle plate adjacent in the direction of rotation of the cylinder, but the lower part is not in contact, the needle plate stacked bodies 18 can be easily arranged in a row.

Further, other examples of the needle plate 16 are shown in FIGS. 4a, b, and c, in which a hole 14 is provided in the needle base 12, and
A hole 20 is also provided in the lower part of the needle insertion part, and this hole 2
0 and the holes 14, 20 of the throat plate laminated with each other or the holes 14, 20.
By inserting resin into the slits 15, they are fixed to form a continuous body to constitute a throat plate laminate. In b, the lower part of the slit 15 is narrow, and by fitting the continuous body into the slit, the fixing can be made stronger. The hole 14 shown in c has a rectangular cross section, and the laminate is more firmly fixed.

Further, the shape of the hole can be various shapes such as a triangle and a square.

The connecting body 17 that fits into the holes 14 and 20 and the slit 15 can be made of a metal rod, a metal plate, a synthetic resin, or a metal rod embedded in a synthetic resin, and can be inserted into the hole from the longitudinal direction. Alternatively, the throat plate laminate is formed by inserting the needle plate from the direction perpendicular thereto.

It is also possible to pour synthetic resin or adhesive, or to use these together with the board.

The groove 10 of the half-lap body and the throat plate laminate 1
8, it is appropriate for the vertical gap to be 0.05 mm or less, and for the horizontal gap to be around 0.1 to 0.2 mm. Conventionally, it was necessary to keep the gap in both the vertical and horizontal directions to 0.05 mm or less, but in the horizontal direction. The gap can be widened.

The combed cylinder half-lap of the present invention has the above-described structure, and the throat plate laminate is fitted into the approximately inverted T-shaped groove, so the vertical gap is small and the throat plate laminate can be inserted easily. It's easy.

Furthermore, compared to the conventional combed cylinder half-lap, the contact area between the throat plate laminate and the groove is wider, so that the holding can be made stronger.

Furthermore, since the grooves are symmetrical, they can be easily machined with an end mill, and the throat plate is also rectangular, making it easy to obtain dimensional accuracy. Furthermore, since the connected body of the throat plate laminate is located almost in the center of the throat plate, the throat plate laminate does not curve to the left or right, making it easy to insert into the groove of the half-lap body. This is an effective invention.
