Description

A device for opening the seam and straightening tubular garments with the inward-facing edges of a longitudinal seam, made in the form of a thin steel ruler inserted manually into the inside of the rolled-up inside and turned inside the tubular product, is known.

The proposed device

provides the opening of the seam in the process of entering the product line, which increases productivity ;; product quality.

For this, the front edge of the ruler is provided with wedge-shaped jaws, having upward-elevated ends and forming a T-shaped groove for inserting the seam edges into it in undisclosed form and withdrawing them in the opened one.

A wedge-shaped plate is attached to the ruler under the jaws, and on its upper part there are two spring straps, which form a longitudinal slit for the opening of the open crevice and elevated above the ruler by the thickness of the workpiece, with the front ends of the slats made in the form of antennae.

FIG. 1 shows a general view of the device; in fig. 2 is a plan view of a device with a tubular sewing product tucked in on it with the designation as I, II, III, IV, V, VI, Vn, VIP, IX, X stages of the process of opening the seam and straightening the product; FIG. 3 shows a sequence for performing the process of opening the seam and expanding the product.

The fixture is a steel ruler with a base in the form of a wedge-shaped plate.

In the front part of the ruler above the plate / wedge-shaped sponges 2 are reinforced with the ends elevated upwards by 2-4 mm, forming the T-groove 3.

On top of the plate / attached are two spring-mounted strips 4 above it, spaced one from another at a distance of about 2-5 mm, in accordance with the thickness of the workpiece. Between the slats 4 there is a longitudinal slit o, and the front ends of the plec noc are made in the form of (ledges) of the antennae b, which form short grooves 7 with the edges of the slats.

In the middle part of the slats 4 there are slots 8. The opening of the seam and straightening of the tubular all-garment, for example, a female coat, is carried out as follows.

After grinding, the seam is not flattened, but it is turned out of the inside out of the inside, after which the front end is fixed by means of the workpiece with the help of the seam up (D031PHII /, operation a), then the sides are slightly opened by hand (position II, operation b) .

The free end of the cage is threaded into the device so that the product's grooves at the place of the strike fit into the T-shaped groove 3, and the crevice sections are located between the wedge-shaped end of the base / and the jaws 2 (position III and IV, operations c and d) .

While the ruler is inserted into the cavity, the ujea slices extend through the transverse part of the T-shaped groove (position G, operation e) to the top of the guide (position VI, operation e) and fall under antenna 6 (position VII VIH, operation / s, h) springs and 1; their plates 4. Then, pulling slightly along with, the ruler is introduced into its cavity along the entire length (position IX, operation and). Position X shows a ruler without a cac (operation k).

T-shaped groove 3 and a slit provide the location of the seam in the midline along the sa.

The expansion of the joint by inserting the ruler into the cavity through the cavity is ensured by the corresponding mutual position of the plate 1 and the T-shaped groove 3 with the jaws 2.

With the ruler inserted into it, it is processed on an ironing press, whereby the pinning of the schV, previously unfolded by a ruler, and the final zatyuzhka of the edges along the entire perimeter are carried out simultaneously.

After processing on the ironing press, the ruler is removed from the ca.

In order to ensure a stable width across sa along the entire length, regardless of the size of the allowance for the slopes, it is ground in the machine using a knife switch.

Subject invention

Claims (4)

1. A device for opening the crevice and straightening tubular sewing products with inwardly facing edges of the longitudinal crevice, made in the form of a thin steel ruler, inserted manually into the inside of the seam from the inside out and turned out of the tricky product, which is different in that ensuring the opening of the joint in the process of inserting a ruler into the product, the front edge of the latter is provided with wedge-shaped jaws having ends elevated at the top and forming a T-shaped groove for entering the edges of the joint in an unopened form and exiting them . 2. The shape of the adaptation according to claim 1, characterized in that, in order to ensure the preliminary opening of the seam, a wedge-shaped plate is attached to the ruler under the jaws. 3. The form for making the device according to claim 1, characterized in that, in order to locate the opening shch in the middle of the product and keep it in the opened form, Two spring straps are attached to the ruler from the top, forming a longitudinal slit for the passage of the opened crevice and raised above the ruler by the thickness of the fabric of the workpiece. 4. The form of making the device according to claim 3, characterized in that, in order to ensure that the open seam extending from the T-shaped groove of the liner extends into the gap between the strips, the ends of the strips are made in the form of antennae.
