Description

[Detailed Description of the Invention] The present invention relates to a reed cap for a loom, and more specifically to an easily adjustable reed cap made of a light alloy such as aluminum.

Traditionally, most reed caps for looms have been made of wood.

However, if the reed of a loom is not attached so that its central part curves slightly backwards, the shuttle will tend to fly out when the reed is run.

Therefore, the shirttle sled is provided with a sweep, and the reed cap is also required to be adjusted to have an arched slope facing the sweep.

Figure 4 is a plan view of the reed area of the loom, where B is the back side of the loom, F is the front side of the front, P is the picker, S is the shirttle, R is the reed, and W is the wood. This is a shirt made by Torsley.

A lead R is installed vertically on the rear surface of the shirtless sleigh W. If this rear surface were connected with a straight line, it should form an L line, but in reality, it takes on the shape of a rear arc like the lead R. An arcuate sweep is provided.

This is because if the reed is placed in a straight line like line L, the flying shirttle will hit and the repulsive force will cause the shirttle to jump out to the front side F, so the lead R will move backwards as shown in Figure 4. This is usually called a sweep.

In addition, due to the heavy beating of the loom, the mounting surfaces of the slay swords on both ends of the reed cap, as well as the front and back clip parts of the reed cap, are severely worn, and the reed angle and sweep angle are affected by cutting these parts. Since the system would go out of order, time-consuming maintenance adjustments were required each time.

However, in the case of conventional wooden reed caps, dexterous and skilled woodworkers are required for the above-mentioned maintenance, and the number of such skilled woodworkers has been decreasing recently.

In this regard, prior art has also been proposed in which the lead cap is made of a light alloy such as aluminum.

Utility Model Application Publication No. 48-100973 is one example.

However, this was merely a simple thin-walled rectangular tube made of a metal plate with the lower surface cut out, and therefore had the defect that it would bend during beating and would not provide sufficient strength.

There is also Japanese Utility Model Publication No. 54-16216.

However, this is related to the attachment structure to the sleigh sword.

It is very difficult to create a desired sweep shape with the front and rear presser pieces that clamp the top of the reed, and this difficulty in adjustment has been the biggest drawback.

In view of the above circumstances, the reed cap of the present invention does not require woodwork maintenance, and the front clip made of flocked material can be easily adjusted to suit the thickness of the reed top and the sweep shape. An example of this will be described below with reference to the drawings.

1 is a sled, and 2 is a sled sword on which the sled is mounted, and the back and forth movement of this sleigh sword causes a whipping motion.

R is the lead, RA is the top, and RB is the bottom.

The reed cap of the present invention has an oval reed top with a protruding reed holder for older looms, but it is also fitted with a circular reed holder Rh that is used for new looms as shown in Figures 1 and 2. You can also attach the top of the reed,
Furthermore, it can also be used as a double lead type.

Both ends of the reed cap are attached to the sleigh sword 2 by angles 3, and the main frame portion 4 of the reed cap is made of a light alloy made of aluminum and has a P-shaped cross section.

This cross-sectional shape is inside the lower edge flange of the P radiation body frame 4.
A long back clip 5 made of wood and having a cross-sectional shape of a 114-circular arc and a sweep shape with a central portion slightly arched backward is fixed with bolts 6, 6.

On the other hand, the one-character block-shaped front clips 7a, 7...7, 7a made of synthetic resin and having a cross-sectional shape of 114 arcs facing the back clip 5 have vertical holes 8...
Nuts 9...9 are embedded in the lower ends of the nuts 9 and are fastened to the P emitter frame 4 from the bottom with bolts 10...10, but the holes drilled in the bottom are , a long hole 11 in the front and back direction so that the front clip can slide back and forth.
...11, and is attached so that it can be adjusted forward and backward.

This single-shaped front clip 7a, 7...7°7a
grooves 12 .
7a are rapidly arranged along the guide rod 13, and can be adjusted in an integral shape.

Note that pins 19 are implanted at both ends of the groove portions 12 of the front clip 7a at both ends to prevent the guide rod 13 from coming out.

A method of handling the reed cap for a loom of the present invention having the above structure will be described below.

Attach the angle 3 to the sled sword 2, then place the reed cap on the angle 3, loosen the bolts 10...10 of the front clips 7a, 7...7, 7a, and remove the top part RA of the reed R. is held between the back clip 5 and the front clips 7a, 7...7, 7a, and the bolts 10...10 are tightened.

At this time, if the lead top part RA is covered with a circular lead holder Rh, the above-mentioned clips can be held by holding the circular lead holder Rh part on both sides instead of holding the lead at both ends as in the conventional method. Since both clips are held in a 1/4 arc shape, there is little wear on the surfaces of both clips, and the safety device is activated by holding the shuttlecock in place.Furthermore, when the lead base RB comes off, the lead top is secured between the two clips. Part RA can rotate smoothly.

As another example, Fig. 3 shows a model without a lead holder, and in this case, the lower ends of the J-shape are clamped with the ends of the long front clips 7'...7' with play in the lead surface. It becomes a shape.

Note that this lead ground portion Rr3 is held between the tip 1/4 arc shape of the flyback 15 attached to the arm 14 and the 1/4 arc shape rear end of the wood slash 16 attached to the sled 1. The above-mentioned safety device is because the arm 14 is rotatably attached to a spike rod 17 that passes directly below the sled.

The above-mentioned front clips 7a, 7...7, 7a are for the elliptical reed top part 7' for old model looms, and for the circular reed top part covered with a reed holder for new looms. If two types are prepared, the front clips can be quickly arranged by sliding freely on the guide rod 13 made of a single spring steel according to the thickness of the lead or along the sweep shape without changing the direction. This makes it easy to adjust the integrated shape.

Note that 18 is a side stopper that controls the left and right movement of the reed.

The keyed cap of the present invention not only allows the lead cap clamping and attachment work to be carried out smoothly as described above, but also has many other effects as described below.

■ The reed can be inserted from below while attached to the sleigh sword on the loom.

■ By using the side stopper and securely tightening the bolts on the front clip, there is no lead shift during driving.

■ The angle of the lead and the mounting accuracy of the top and bottom are high, and no special experts are required.

Furthermore, the front clip can be integrally adjusted along the back clip and the corrected sleeve shape, making it possible to stably hold the lead.

■ Since the reed is held between the back of the reed cap, the distance between it and the first belt frame is widened, making it easier to thread the warp when the thread breaks.

■ Wear on various parts has been significantly reduced, and maintenance repairs and adjustments are now almost unnecessary.

The lead cap of the present invention is revolutionary in that it solves the problems of maintenance, durability, and workability, which were the biggest problems in the past, and is also useful and practical. It is highly sexual.
