Description of the Invention (/) The present invention relates to a method and a device for manufacturing a pouch or a pocket, especially a document cover. However, although it is more specifically designed for this purpose, it can also be used to make other kinds of pouches or pockets. At present, it is a conventional practice to make a pocket to hold a document by using two rolls of prefabricated film, the width of which is roughly equivalent to the width of the pocket. The films are unrolled in parallel, facing each other, then welded and cut into the desired format. It is also known to use a roll of film which is approximately twice as wide as the final width of the pocket. The film itself is first folded back to form two opposing pieces of material, which are then welded and cut using the same techniques as above. In terms of this solution, if you want to increase the capacity of your pockets, you have to increase your production equipment, which of course leads to higher costs, not only because of the purchase of machines and their operation, but especially because of the floor area that must be used to install them , Or due to the adjustment time involved. It should also be noted that this solution must provide the transport and storage of film rolls between their place of manufacture and their place of use, which leads to a lot of problems' especially because of the risk of damage during processing or if the film is left in a warehouse Too long and aging to lose its flexibility. In addition, each time the film roll is changed, production must be discontinued, which affects the final cost of the product. The purpose of the present invention is to provide a method and a device for manufacturing a pouch or a pocket, in particular to protect a document cover, which overcomes the aforementioned disadvantages and can optimize the required production equipment. 3 4 This paper size applies to Chinese National Standards (CNS) A4 specifications (210 X 297 g). --- ^ --.------ III ----- (Please read the precautions on the back before filling out this page) Employee Cooperatives, Intellectual Property Bureau, Ministry of Economic Affairs Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs of the Consumer Cooperative Cooperative Association * J7 B7 V.

Description of the Invention A strip of material 4 is provided, which is intended to constitute the pouch or pocket 1. The width Lb of the strip 4 is at least four times larger than the size of one side of the pouch or pocket 1 or the so-called "multiplied size" Lb. This size is for example their width. The material strip 4 constitutes a web 7 '. Each longitudinal side 8, 9 of the web 7 has a region 10, 11 with a double-thickness material, or a "double-thickness region", whose width Lz is equal to or greater than the Multiply the size Lp. The pouch or pocket 1 is individually formed in each of the double-thickness regions 0, U. The pouch or pocket 1 is then formed in the same strip of material 4, which makes it possible to use conventional production equipment in each double-thickness zone 10,11. In this case, with a series of driving devices 12, 13, the web 7 is caused to travel at least in the direction of the arrow 50, and the web is separated into at least two parts 14, 15 in the length direction. The special condition is approximately equal width, This is the furthest downstream possible with respect to the direction of travel 50 of the material strip 4 and, more specifically, it is just upstream of the drive 13 which is furthest downstream. The risk of offset between different separation sections 14, 15 is prone to appear in different stretch conditions, and is thus reduced. According to an embodiment of the first form, the strip 4 is in the form of a sleeve to delimit a web 7. According to another form of embodiment, the strip of material 4 is first caused to travel straight in the direction of its longitudinal axis 3, and the longitudinal edges 5, 6 of the strip 4 are folded back inward to form the web 7.
