2. Description of the Related Art When processing a band-shaped fabric that has been left in a folded state as a processing target, a crooked portion such as a fold is formed at the folded portion. There is a danger that the portion may be bent and the fabric cannot be grasped accurately, or may be warped at the overlapped portion or the butt portion, so that the fabric cannot be processed into a normal annular fabric. In order to solve this, for example, it is conceivable to remove the habit by extending the entire dough in advance and leaving it unattended, or to apply a heat and pressure treatment to the entire band-shaped dough with a heating roll or the like while feeding out the dough. Not a little, but in the former case there is a huge waste of space and time, and in the latter case, in addition to consuming a large amount of heat energy, the processing speed of the entire belt-shaped fabric is increased by heating and pressing. There is a problem of being restricted by time,
In each case, the practicality was lacking. Therefore, conventionally, as shown in FIG. 26, this kind of annular dough manufacturing apparatus has a heating and pressurizing method at a specific position on the upper side of the cutting device 3 in a dough supply path K having a fixed length. There is a device in which the apparatus 9 is installed in a fixed state, and when the cutting point of the band-shaped cloth is approaching the press point of the heating and pressurizing apparatus 9, the cloth feeding to the cutting apparatus 3 is interrupted.
The heating and pressurizing treatment was performed.

[0003]

According to the above-mentioned conventional apparatus for manufacturing annular cloth, as shown in FIG. 26, a band-shaped cloth a having a cutting length dimension M is supplied to a cutting apparatus 3, and the band-shaped cloth is manufactured. If the portion to be cut of the band-shaped fabric a is located at the press point of the heating and pressurizing device 9 in a state where the feeding of a is stopped, the cutting step and the heating and pressing step are performed at once as it is. However, when the set value of the cutting length dimension M is changed, in each process, the point at which the feeding of the band-shaped cloth is stopped is shifted, and accordingly,
There is a problem that the number of times of stopping the feeding of the belt-shaped cloth and the number of times of re-feeding are doubled, and the manufacturing efficiency of the whole ring-shaped cloth manufacturing process is reduced. That is, when the feeding of the band material to the cutting device 3 is completed (when the feeding is stopped), a portion other than the portion to be cut of the band material is located at the press point of the heating and pressing device 9. (See FIG. 26 (b))
In order to heat and press the portion to be cut, after the cutting process is completed and the feeding of the band material is reunited, at the time when the portion to be cut of the band material approaches the press point,
Since it is necessary to stop the feeding of the band-shaped fabric and apply heat and pressure (see FIG. 26 (a)), as a result, the feed stop and reunion operation for the cutting process and the feed stop / The reunion operation must be performed separately in a series of annular fabric manufacturing processes.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide an apparatus for manufacturing an annular cloth capable of efficiently forming annular cloths of various sizes.

In a state in which the band-shaped fabric is supplied to the cutting device for a set length, a path adjusting means is provided so as to be adjustable so that a portion to be cut of the band-shaped fabric is located at the place of the heating and pressurizing device. Even if the cutting length dimension set by the length adjusting means is changed to various values, heating is always performed in a state where the strip-shaped cloth for the cutting length dimension is supplied to the cutting device and the feeding is stopped. The length of the first dough supply path can be adjusted by the path adjusting means so that the portion to be cut of the band-shaped dough is located at the press point of the pressing device. As a result, the feed stop and reunion operation for the cutting process and the feed stop and reunion operation for the heating and pressing process are

There is an advantage that the bonding failure of the fabric can be reduced.

According to the characteristic configuration of the second aspect of the present invention, since the path adjusting means changes the linearity of the first cloth supply path, for example, a plurality of cloth support rollers are provided, and a belt-shaped In the case where the first dough supply path is configured to wrap around the dough, the position of the dough support roller can be adjusted in the radial direction only by adjusting the length of the first dough supply path. It is possible to change and adjust,
The route adjusting means can be configured with a simple mechanism. As a result, an increase in the cost of the device itself can be suppressed.

According to the characteristic configuration of the third aspect of the present invention, the path adjusting means sets the path length dimension of the first cloth supply path to the band-shaped cloth cutting length dimension set by the cutting length adjusting means. Since it is formed so as to be able to be set in conjunction with an integral multiple of the length of the fabric, only by setting the cutting length dimension of the band-shaped cloth by the cutting length adjusting means, the press point of the heating and pressing device is adjusted accordingly. Since the path adjusting means interlocks with a state in which the portion to be cut of the belt-shaped cloth is coincident, the operation and effect corresponding to the invention of claim 1 can be achieved without any trouble, and the operability of the apparatus is improved. It is possible to do.
