Abstract

An elastic fastener has a longitudinally cut loop in a flattened chamber of used air. An Independent claim is included for the following: (a) Manufacturing an elastic fastener as above by flattening the chamber and cutting the loop longitudinally. Preferred Features: The cutting is done using a tool attached to a press.

Description

<U>Procédé de fabrication d'attaches plates.</U> <U> Flat fastener manufacturing process. </ U>

La présente invention concerne un procédé de fabrication d'attaches plates en matière élastique à partir de chambres à air usagées à recycler. The present invention relates to a method for manufacturing flat fasteners of elastic material from used air chambers to be recycled.

I1 est connu de recycler les chambres à air en matière élastique pour former des attaches élastiques. Ces attaches sont ménagées par une découpe transversale en rondelle de la chambre à air. It is known to recycle inner tubes of elastic material to form elastic fasteners. These fasteners are provided by a transverse slice cut of the inner tube.

La présente invention a pour but de proposer un nouveau procédé de fabrication d'attaches plates à partir de chambres à air à recycler dont le coefficient d'élasticité est supérieur aux attaches de l'état de la technique. The object of the present invention is to propose a new method of manufacturing flat fasteners from air chambers to be recycled, the elasticity coefficient of which is higher than the fasteners of the state of the art.

A cet effet, la présente invention consiste en ce qu'on pose à plat la chambre à air et on découpe un anneau longitudinalement dans la chambre à air posée à plat. For this purpose, the present invention consists in that the air chamber is laid flat and a ring is cut longitudinally in the air chamber laid flat.

De cette manière, on obtient des attaches plates de forme beaucoup plus large et de grande longueur tout en présentant un coefficient d'élasticité élevé. De préférence, la découpe est obtenue à l'aide d'un outil de coupe présentant la forme et les dimensions souhaitées pour l'attache et monté à l'extrémité d'une presse. La chambre à air étant posée à plat, lorsqu'on abaisse la presse, on découpe deux attaches en même temps. In this way, flat fasteners of much wider shape and length are obtained while having a high coefficient of elasticity. Preferably, the cut is obtained using a cutting tool having the shape and dimensions desired for the fastener and mounted at the end of a press. The air chamber being laid flat, when the press is lowered, two fasteners are cut at the same time.

La présente invention a également pour objet une attache plate en matière élastique, caractérisée en ce qu'elle est constituée d'un anneau découpé longitudinalement dans une chambre à air à recycler posée à plat. The present invention also relates to a flat fastener of elastic material, characterized in that it consists of a ring cut longitudinally in a recirculating air chamber laid flat.

Une attache obtenue selon le procédé de l'invention est utilisée de manière particulièrement avantageuse pour maintenir fermés des emballages tels que des casiers à crustacés ou à huîtres. A fastener obtained according to the process of the invention is used particularly advantageously to keep closed packages such as crustacean or oyster trays.

Une telle attache plate présente l'avantage de ne pas présenter de surépaisseur, ce qui favorise la stabilité des chargements de casiers munis de telles attaches.Such a flat fastener has the advantage of not having excess thickness, which promotes the stability of loads of lockers provided with such fasteners.
