Abstract

A protective glove, includes a double wall produced by welding four plastic layers. Both inner film layers are welded to form the inner glove, and the two outer film layers are welded together to form the outer glove. The outer film layers pref. have different characteristics and/or colours to the inner layers. ADVANTAGE - The glove is economical to produce and does not leak.

Description

The invention is directed to a protective glove Welding using four superimposed ones Plastic film layers is double-walled.

It also relates to a method for producing the protective hand shoes and a device for producing the protective glove or to perform the procedure.

To produce loose gloves of the aforementioned type, two Foil sheets laid on top of one another and contours by means of separation welding together in an electrically heated welding station added. The welding electrode determines the contour of the glove. The finished glove is processed loosely - usually by hand works. In a more automated process, the sweat heat of the glove production also used to the finished Seal the glove on a moving paper web. In one re-clocked operation is then the paper with the on it sealed glove in a folding machine with high speed folded exactly and consistently, and a so-called machine-compatible service pack manufactured.

With cheap gloves of this type can always be flawless Quality of the weld seam - as a result of dirt inclusions, tem fluctuations in temperature, machine stop or running-in problems - in general common are not guaranteed. Leaks can also be caused by mechanical overstretching occurs during use. Because above all  the weld seams can be a source of error by stabi ler foils or multi-layer layers welded together, such as known from DE 88 02 134 U1, a noteworthy improvement cannot be achieved.

If protective gloves of better quality, in particular Guaranteed tight gloves are required after diving procedures are worked. In the immersion process, a ge powdered metal vulcanizing mold into a liquid plastic mass, e.g. B. dipped in vinyl or latex. When pulling out the Mold from the immersion bath remains a plastic film on the mold With compressed air support, this is after the Vulcanize manufactured glove removed from the mold and packed up. The manufacturing costs in this process are Manufacture of individual, loose gloves much higher than with Manufacture of welded gloves. Additional manual labor gears are required to form service packs.

The invention has for its object a ge from foils to create welded protective glove, which according to the cost cheap welding technology is and still one Security against leaking like a submerged glove tet.

In the case of a protective glove of the type mentioned at the beginning, this is Object achieved according to the invention in that the two inner Foil layers with forming separation welding to one palm shoe and the two outer layers of film around the inner glove around with forming separation welding to an outer glove are welded.  

With the invention is a by the separation welding process in shape of a double glove cheap glove suggested gene consisting of two individually welded parts, namely one Inner glove and an outer glove, which is already at Manufacture are intertwined. Manufacturing requires so no additional manual assistance. Of course it can one or another weld seam in the glove according to the invention leak or become, but it is unlikely that one and the same glove two seams defective at the same time are or will be. With that of cheap glove manufacture effort, a density guarantee can therefore be achieved otherwise it could only be achieved with dipped gloves.

As I said, the two parts of the double according to the invention gloves do not have a welded joint. This statement is to be put into perspective, because of course it only applies to those entire finger and hand areas, i.e. where it is on good Tightness arrives. For reasons of practical handling, e.g. B. when putting it on, however, it can be beneficial if the palm of your hand shoe and the outer glove at the inlet of the glove cuff once connected around the arm area, esp special welded, are.

Another advantage of the protective glove according to the invention can can be obtained if the outer glove is made of other foil shafts and / or colors than the inner glove. Then errors are easier to identify; different materials for the outer and inner skin also leave the combination of one for the hand pleasant inner material with the each Best suited to the application.  

Accordingly, a particularly cheap protective glove is characterized net by the combination of a wear resistant material of the Outer glove with a chemically resistant material on the inside glove. Combinations of this type can be found in many areas technical, laboratory, commercial, etc. in advertising and Take advantage of practice. For example with a wear-resistant, hard outer glove combined with a chemical-resistant, soft inner glove means mechanical damage to the Outer glove by no means the loss of protection.

A further advantageous embodiment of the object according to claim 1 results from the features of claim 4.

The inventive solution to the above object is for the procedure for manufacturing a protective glove at the beginning mentioned type in that a first outer glove film and both Inner glove films laid flat on top of one another for manufacturing of the inner glove serving first separation welding station be, and that the first outer glove film within the loading Reichs the first separation welding station at a distance from the adjacent inner glove film held and the inner glove is welded in this position.

The manufacturing steps are in the method according to the invention for welding the inner and outer gloves together fits each of the gloves one from the other's weld completely separate weld sits. The separate production of the two welds makes although an additional welding station is required, it is guaranteed but provides a high tightness of the entire glove that is called the double glove according to the invention. You would namely when welding only two double layers of foils to one Unite glove would be a certain improvement in To achieve firmness of the glove surfaces, the manufacturer  but could hardly be a bigger one for the quality of the welds Take over guarantee than with protective gloves with simple wan dung.

The method according to the invention hardly requires any additional ones Effort compared to the conventional manufacturing process simple contour welded protective gloves made of foil, it is namely only necessary, which already exist between the to put the welding glove through the inner glove led an outer glove film in the process of ver welding the inner glove from the adjacent inner hand separate the shoe film so that a welded connection between these two slides cannot occur.

Another improvement or refinement of the fiction Appropriate method is that after the separation welding of Inner glove the second outer glove film on the next moving foils containing the finished inner glove and in the area of a second welding station is moved and that there the outer glove by separation welding of the superimposed outer glove films around the finished one Inner glove is welded around. An essential one in this Process step gained advantage is that the second or when welding outer glove film on top, without to get into the working area of the first welding station at all men and there to disturb the film package only between the two Welding stations is to be fed. This also gives you the front part that already after the first welding process Ab fall off without hindrance through the second outer glove film are transported. This intermediate cleaning may help Eliminate sources of error in the second welding process.  

The method described can still according to the invention can be further improved if used to manufacture the outer hand welding heat used to seal the fer term glove used on a paper web or the like becomes. Such a dop according to the invention sealed on paper Fur gloves can be simply welded gloves as before to a mechanically exactly folded sealing package ten, so that the method for producing an invented double glove according to the invention in conventional produc roads can be integrated.

For the device for producing the protection according to the invention glove or to perform the manufacturing process a protective glove is the solution to the above problem characterized by a film feed and transport track with a first and a second, the glove contour Separation welding station, through foil feeds for stacking opening put two inner glove films on top of each other on a first outer one glove film in front of the first separation welding station and for opening place a second outer glove film on top of the palm shoe foils after the first separation welding station and through an in Area of the separation welding station between the first outer glove foil and the adjacent inner glove foil plate.

One for making the double glove according to the invention pulled device thus only requires an additional Welding station and in the area of the first welding station Separating plate between the first outer glove film and the bordering inner glove film. This one for mass production relatively little effort translates into production costs per  Glove so little noticeable that one of the invention separately welded glove-in-glove as well as from early Here are individually welded gloves from a cheap glove can speak. The double glove according to the invention has what its stability and density concerns properties that those dipped gloves, e.g. B. by designing the outer film in Ratio to the inner film, can easily exceed.

According to a further invention, the separating plate placed in the first separating welding station between the lower outer film and the adjacent inner film is made of polytetrafluoroethylene or the same low-friction material or is coated with such a material. It is thereby achieved that the foils are to be guided close to one another - only at a distance from the thickness of the separating plate - through the area of the first welding station, without the risk that the first outer foil would be unintentionally connected to one of the inner foils.

Based on the schematic representation of an embodiment details of the invention are explained.

In the drawing, a device for producing protective gloves is shown in principle. A transport path 1 are successively a first outer glove film 2 , a first inner glove film 3 and a second inner glove film 4 - for example, each from a roll - fed and moved in the transport direction 5 to a first separation welding station 6 . The latter contains a welding electrode which can be moved up and down in the direction of the arrow 7 . A separating plate 8 is located in the area of the first separating welding station 6 - spatially essentially fixed. The first outer glove film 2 runs underneath half of the separating plate 8 , while the two inner glove films 3, 4 above the plate, the welding electrode of the separating welding station 6 , are moved forward in the transport direction 5 .

In the first separating welding station 6 , the two flat, mutually flat film webs, namely the first and second inner glove films 3, 4 , are joined with an electrically heated welding electrode according to the contours, without the first outer glove film 2 running below the separating plate 8 being adversely affected by the welding process. Following the first separation welding process, any remaining film can be disposed of with the aid of a suction system 9 or the like. The still simple inner glove 10 produced in the first separating welding station 6 should only consist of parts of the two inner glove films 3, 4 and should not be connected at any point to the first outer glove film 2 by welding.

After welding the inner glove 10 in the first separation welding station 6 and, if necessary, after removing any waste which could cause errors in the weld seam of the associated outer glove 13 , a second outer glove film 11 is placed on the inner glove 10 containing the finished inner glove 10 in the transport direction 5 Sheets 2 to 4 placed on the transport track 1 in the area of the second separation welding station 12 . There, the outer glove 13 is welded around the finished inner glove 10 by welding the outer glove films 2, 11 lying one on top of the other. The just in the direction of arrow 7 lowerable or raisable welding electrode of the second separating welding station 12 is designed such that no welding connection to the inner glove 10 occurs when the outer glove 13 is produced. The weld seams surrounding the two gloves 10, 13 should therefore be as independent as possible from one another, such that if an error occurs in one of the weld seams, the probability of an error in the respective seam remains as low as possible. However, the double glove 14 can have a z at the inlet 15 of its sleeve. B. once around the arm area connection of inner and outer gloves 10, 13 in the weld area. For the rest, the inlet area of the double glove 14 in the area of the wrist is basically unwelded, ie it is formed by the foils which are not welded to one another in this area.

The finished glove-in-glove or double glove 14 according to the invention is - optionally together with the remaining foil package - moved further along the transport path 1 in the transport direction 5 and cleaned of any loose waste with the aid of a second suction system 16 .

If, together with the foils 2 to 4, a paper web 17 - in principle in the manner shown in the drawing - is placed on the transport web 1 , the finished double glove 14 can be welded to the second separation welding station 12 by the heat of welding used to produce the outer glove 13 Paper web 17 are sealed. In this case, the double glove 14 , preferably in pairs, sealed onto the paper web 17 can automatically be further processed into an exactly folded sealing package. Corresponding devices can follow in the direction of arrow 18 .
