Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method of attaching a background fabric to a frame used in an embroidery process.

[Conventional technology]

In the conventional industrial embroidery process, an embroidery frame consisting of an inner frame and an outer frame is used to stretch a base fabric, and the required number of frames covered with the base fabric are attached to an automatic sewing machine equipped with many sewing sections. The embroidery machine is fitted and fixed in a predetermined position on a frame base, and the frame base is fed into the sewing section of an automatic sewing machine, and the automatic sewing machine is operated to embroidery the fabric stretched on each frame. .

In such an embroidery process, sewing by an automatic sewing machine is efficiently performed according to a computer program.

[Problem to be solved by the invention]

However, the work performed before sewing with an automatic sewing machine, that is, the work of stretching the base fabric onto the frame, is done manually, and this work involves removing the inner frame from above the outer frame covered with the base fabric. This is a process of sandwiching the fabric between the inner frame and the outer frame by pushing it into the frame, and it involves placing the part of the fabric to be embroidered accurately at a predetermined position inside the inner frame, and It takes time and effort to adjust the tension of the cloth appropriately. Therefore, the work of stretching the fabric onto the frame reduces the operating efficiency of the entire embroidery process, and is one of the causes of the loss of economic efficiency.

In addition, if the mounting method involves sandwiching the ground fabric between the inner frame and the outer frame, marks from being sandwiched between the inner frame and the outer frame tend to remain on the ground fabric, which reduces the product value. I was also worried. Therefore, it is not preferable to employ such an attachment method for high-quality cloth.

This invention was made in view of such circumstances, and it makes it easier to automate the work of pasting the base cloth on the frame and the work of fixing the frame with the base cloth stretched to the frame base, and it also leaves no attachment marks on the base fabric. To provide a method for attaching ground fabric to a frame in an embroidery process without leaving any residue.

[Means to solve the problem]

The method for attaching the background fabric to the frame in the embroidery process of this invention is as follows:
A base cloth is pasted on the surface of the frame coated with adhesive, and the frame is fixed to the frame base.

[For production]

According to this method, the base fabric is not sandwiched between the inner frame and the outer frame, so there is no room for traces to remain on the base fabric, and it is also easier to adjust the tension and attachment position of the base fabric than in the past. This makes it easier and more automated.

〔Example〕

The method for attaching the background fabric to the frame in the embroidery process of this invention is as follows:
A base cloth is pasted on the surface of the frame coated with adhesive, and the frame is fixed to the frame base. The term "adhesive" as used herein is meant to include all substances that stick things together, such as glue, synthetic resin, and double-sided adhesive tape.

For example, as shown in FIG. 1A, the frame 1 to which the base fabric is pasted is constructed by forming an opening 11 in a rectangular plate for pasting the base fabric, but the outer shape of the plate is such that the frame 1 is fitted into the frame 1. The frame support of the frame base (described later) for inserting and fixing the frame is changed as appropriate depending on the shape of the part. Further, the shape, size, and number of the sekiguchi 11 are changed as appropriate depending on the area to be embroidered on the ground fabric and the number of locations to be embroidered. Therefore, for example, a plate having two openings 11.11 as shown in FIG. 1C may be used as the frame 1.

In the frame 1 shown in FIGS. 1A and 1B, a pedestal 12 is provided at a predetermined location on the back surface thereof. By doing so, when the adhesive is applied to the surface of the frame 1, it is convenient that the adhesive will not adhere to the frame work of the adjacent tier even if the frames 1 are stacked as shown in Fig. 1D.

An adhesive 2 is applied to the surface of the frame 1. The adhesive 2 may be applied to an area around the opening 11 as long as it is an area to which the base fabric can be reliably pasted. Opening 1 as shown in Figure 1C
The smaller the area of the formation point 1.11 is, the more advantageous it is that a larger area can be secured for attaching the background fabric with the adhesive 2. Note that the application of the adhesive 2 can be easily automated by employing a method using a roller or a brush.

As shown in FIG. 2, the ground fabric C is pasted on the surface of the frame 1 coated with adhesive 2, and preferably oiled paper is layered under the ground fabric C for convenience during sewing. When pasting on the surface of the frame 1, it is necessary to appropriately adjust the position of the background fabric relative to the opening 11 and the degree of pasting. This operation is easily automated by mechanically stretching the background fabric and pressing it against the surface of the frame 1 coated with the adhesive 2.

The frame 1 to which the ground cloth C is pasted is placed on the frame base 3 as shown in Fig. 3.
The frame holder is fitted into the part 31 and fixed.

The ground cloth C is pasted on the frame 1 with adhesive 2, and its adhesion and position are fixed, so the frame holder is inside the frame 31 and the frame holder is inside the frame 31. It is only necessary to ensure that the ground fabric C does not shake, and it is not necessary that the ground cloth C be strongly clamped between the frame support portion 31 and the frame 1. Therefore,
There are no traces left on the ground cloth C due to clamping. Note that the frame 1 may be attached and fixed to the surface of the frame stand 30.

As shown in FIG. 4, the frame base 3 has a plurality of frame holder parts 31, and each of the frame holder parts 31 is provided with a stopper 32. Therefore, the frame 1 is reliably fixed to the frame receiver part 31 by fitting the frame l into the frame receiver part 31 and rotating the stopper 32 in the direction of the arrow mark.

After fixing the frame 1 with the ground fabric C pasted to the frame 3, the frame 3 is fed into an automatic sewing machine having many sewing sections, and the fabric C is attached to the computer program through the opening 11 of the frame 1. The embroidery is done accordingly.

After the embroidery process is finished, the frame 3 is pulled out from the automatic sewing machine, and the frame 1 is removed from the frame 3.

Then, the embroidered background cloth C is peeled off from the surface of the frame 1.

When the adhesive 2 coated on the frame 1 becomes dirty with lint from the base fabric C or the adhesive strength of the adhesive 2 itself has weakened, wash the adhesive 2 with a solution such as thinner. , apply adhesive 2 again. A suitable cleaning solution for the adhesive 2 is one that does not contain formalin.

〔Effect of the invention〕

According to this invention, the time-consuming work of inserting the background fabric between the inner frame and the outer frame while adjusting the tension and position of the background fabric as in the past is eliminated, and the work is much easier and easier than before. The pasting of the background fabric can be carried out accurately.The background fabric can be attached to the frame by just a simple operation, and the process of applying adhesive to the frame and cleaning it can be easily automated. This has the effect of easily automating the installation work to the frame. It also has the effect of not leaving any marks on the ground fabric.
