Abstract

PURPOSE: To spread the back of a pair of fabric layers without rearranging a fabric in every completion of spreading operation and to improve an operation efficiency by using a rotary turret for holding a supporting member for fabric roll and a spreading and cutting apparatus integrally rotatable with the turret. CONSTITUTION: A fabric 9 supported by a supporting member 10 for fabric roll fixed to a rotary turret 7 is spread on a spreading table 4 by a spreading and cutting apparatus 6 and cut. Then the rotary turret 7 is rotated and driven, a guide part 8 attached to the turret 7 and the spreading and cutting apparatus 6 are positioned on a vertical line passing a guide part 5'. The spreading and cutting apparatus 6 is moved again to the lower part of a frame 2. A carriage 1 is driven to the central part of the spreading table 4 and the back of the fabric 9 is spread on the spreading table 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a fabric roll support carriage for spreading fabric onto fabric spreading tables such as those used in tailoring shops.

(Prior art) As is already known, in order to produce clothing items, before cutting, layers of fabric are stacked and aligned,
A so-called fabric mat with a certain thickness is formed.

This preliminary work step is effectively carried out in a semi-automatic manner using a spreading table with a reciprocating fabric roll support carriage.

It is also known that, in the production of expensive clothing, it is necessary to cut the fabrics in a stack to separate each fabric into a left-hand part and a right-hand part.

To accomplish this, it is necessary to unroll both sides of the fabric layer, i.e. to previously rotate the fabric roll support turret through approximately 180°.

On the other hand, in order to rotate the turret of a conventional fabric spreading machine, it is necessary to remove a portion of the fabric from the fabric cutting device beforehand. After rotating the turret, it is therefore necessary to feed the machine with new fabric by holding the starting part of the fabric to be spread on a fabric fixing device provided on the aforementioned cutting device.

Repositioning fabric in this manner is not only time-consuming, but also results in significant fabric waste, as the edges of the new fabric are often flush with the edges of the already unfolded fabric layer. will occur.

A principal object of the invention is to overcome the problems set forth in item 1 above by providing a fabric roll support carriage specifically designed to facilitate the spreading of the back side of a pair of fabric layers. It is to be.

Another object of the invention is to provide a fabric roll support carriage configured to spread fabric in a fully automatic manner.

Yet another object of the present invention is to provide a fabric roll support carriage to eliminate any fabric waste.

(Means for Solving the Problems) According to the present invention, the above-mentioned main purpose is to provide a rotary turret that supports a support member for a fabric roll, a rotary turret that is slidably provided on a vertical shaft guide portion, and rotates integrally with the rotary turret. This is achieved by a fabric roll support carriage for spreading a fabric roll on a spreading table, characterized in that it has a cutting device configured to operate preferably up to its bottom.

(Operation and Effect) Therefore, the work of rearranging the fabric can be omitted, and work efficiency is improved.

Further features and advantages of the fabric roll support carriage according to the invention will become clearer from the following detailed description of a preferred but non-limiting embodiment, with reference to the accompanying drawings. DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an improvement of a fabric roll spar carriage according to the invention, designated generally by the reference numeral 1. FIG. It has a carriage frame 2 with a control panel 3 and is configured to reciprocate along a spreading table 4 of conventional type.

The two opposing walls of the frame 2 are provided with a corresponding pair of vertical shaft guides 5, 5' in a direction perpendicular to the driving direction, which slidably regulate the fabric roll spreading/cutting device 6. .

Above the frame 2 there is provided a rotating turret 7, also of a substantially known type, whose upper surface is of the same size as the frame 2.

The rotating turret 7 supports a pair of vertical shaft interiors 8 on one of its main walls, the axis of which is aligned with the aforementioned wealth interior pair 5, 5.
One side of ゛ is concentric with the axis of 5. In particular, the aforementioned pair of guides and the spreading device are configured such that the device operates at regular time intervals along the guides.

In order to operate this device, a drive rack (not shown) is provided which abuts the lower interior 5,5° and the upper guide 8;
It is also possible to arrange two driven sprockets connected to the spreading device 6 to cooperate with the rack.

During operation, a first fabric layer is spread on the spreading table 4 (the first
Figure) After cutting the fabric with the spreading cutting machine W6, this machine
As shown in FIG. 2, the rotary turret 7 is driven along a guide portion 8 provided on the rotary turret 7.

Then, the turret 7 is rotated (see Figures 3 and 4).
), the guide section 8 and the spreading device 6 are positioned on a vertical line passing through the guide section 5'.

It should be noted here that this rotational operation is effectively carried out while the carriage 1 is being displaced to the end of the table 4, which is the position where the spreading of the fabric to be cut begins. Next, the fabric spreading device W6 is moved again to the lower part of the frame 2, and the carriage l is driven toward the center of the spreading table 4, and the fabric layer on the opposite side, that is, the fabric on the back side of the side that has already been spread, is Extend the strata.

By means having the structure and function as disclosed,
The fabric 9 supported by a support member 10 fixed to the rotating turret 7 is always fixed to the cutting device 6 until the spreading operation is completed.

Therefore, the wasted time of collecting the fabric and placing it on the machine after each spreading operation is completed is completely eliminated, and there is also no waste of fabric.

Additionally, an electronic control device may be provided to provide extremely accurate alignment in both the weft and warp directions.

From the above disclosure, it will be appreciated that the present invention satisfactorily achieves its intended objectives.

Although the invention has been disclosed with reference to a preferred embodiment, it will be obvious that certain modifications and changes may be made within the scope of the appended claims. Dew.
