DE1150634B - Process for the production of work gloves for the metal industry - Google Patents

Description

The invention relates to a method for producing work gloves for the metal industry. These gloves are subject to mechanical processing as well as electrical and gas welding and cutting of metallic workpieces, and especially when punching, Pressing, cutting and similar processing of sheet metal subject to extremely high loads. Above all, the sharp cutting, punching and cutting edges of the sheets make it extremely quick Wear and tear.

It is known that the durability of the gloves by appropriate design and reinforcement of the To increase the grip surfaces and the seams. Because the seams are the most destructive are exposed and are crucial for the lifespan of the gloves, you have them through Laying out of the palm, by sewing inwards, by sewing tucks in between and Protected against mechanical and heat influences by covering with beads and plastic films.

These procedures have largely proven themselves; however, they have considerable disadvantages. They increase the manufacturing cost, require careful work, in addition to that used for mass production Semi-skilled workers are rarely able, and those produced with the processes just described Gloves are stiffened at the seams, especially when beads and foils are applied, and as a result less easy to move.

The desired seam protection can only be achieved to a limited extent by laying the seams inwards, and, moreover, this method cannot always be used, for example for Multi-finger gloves outer seams are mandatory.

With these gloves in particular, it is also possible to produce them from just a few pieces and to bring the joints and thus the seams out of the danger area.

It is also not new to tighten the threads of work gloves when sewing so tightly that they come in penetrate the leather. But since the threads are only a little below the surface of the glove cover be pulled down and experience has shown that most of the time while sewing, with certainty If you stretch heavily during use, you are only slightly protected from damage.

For sewing parts made of rigid leather, especially harness and shoe soles It has long been customary to countersink the seams by means of pressure rollers. Cutting knives Method of manufacture

or by means of lateral wedge-shaped approaches of the sewing needles in the leather grooves, on their Reason then the seams are pulled down while sewing. In this way the seams are against premature Destruction in the case of wear and tear of the leather goods protected.

Despite the many years of knowledge of these measures, the professional world has not yet gone over to to protect the seams of the work gloves in a similar way, in particular by cutting thread grooves. This is explained by the fact that the work gloves are usually made of supple leather, e.g. B. split leather that With these soft leather types, the pressing in is more permanent due to their flexibility and elasticity Thread grooves is not possible and that the clean cutting of grooves in such leather is obvious did not think possible.

The invention aims to be simple and to overcome the above concerns Process for the production of for the metal industry, in particular the sheet metal processing industry from certain gloves, their Seams are optimally protected against damage and have no pressure points.

It consists in the fact that the parts to be sewn together are made of supple leather and are large Tear resistance, for example work gloves made of split leather on both sides with vertical or Incisions directed obliquely to the leather surfaces and reaching up to about 30 to 35 ° <Ό of the leather thickness are provided, and that the sutures are then introduced into the incisions.

In addition to the advantages already mentioned, the bilateral nature of the incisions means that the

The seams of the gloves are always equally well protected, regardless of whether they are worn on the left or on the right. As a result, the worker can use the gloves grab it immediately without having to choose. It also increases the lifespan of the gloves the possibility of use on both sides is significantly increased.

The use of supple leather with high tear resistance finally has the advantage of that the parts of the leather top layer adjacent to the seams are subject to pressure and sliding stress Joint particularly tightly at the incisions and completely cover the seams.

An advantageous further development of the method according to the invention is that the puncture points of the seams, for example by using needles with a sword-shaped point, are elongated and placed as close as possible next to one another, and that they are preferably made of an elastic thread, such as linen thread 25/3 or an endlessly produced plastic yarn threads are pulled so tight when sewing that they the bridge points between the. Press down the puncture sites. In this way, the seams are drawn into the leather particularly well, so that experience has shown that the seams can only be damaged or destroyed when the leather surrounding the seams has become almost completely worn or defective.

For extremely heavy loads or when used For leather types of lower toughness and abrasion resistance, it may be advisable to cut the cut surfaces after the sutures have been brought in using a firmly adhering and supple To stick together adhesive. As a rule, however, the gloves produced according to the invention hold up Even without gluing the cut surfaces, heavy loads are far above average Lifetime stood.

Claims (3)

PATENT CLAIM: 1. A process for the production of work gloves for the metal industry, in particular for the sheet metal processing industry, characterized in that the parts to be sewn together of the supple leather of great tear strength, for example made of split leather, work gloves on both sides with perpendicular or oblique to the leather surfaces directed and up incisions reaching about 30 to 35 ^fl / <> the thickness of the leather are made, and that the seams are then introduced into the incisions. 2. The method according to claim 1, characterized in that the puncture points of the seams, for example by using needles with a sword-shaped tip, elongated and are introduced as close as possible next to each other, and that the preferably made of an elastic yarn, such as linen thread 25/3 or an endlessly produced plastic thread threads are pulled so tightly during sewing that they press down the bridge points between the puncture points. 3. The method according to claims 1 and 2, characterized in that the incision surfaces are glued together after the seams have been introduced.
