Definitions
- the present invention relates to a method for making bags made of paper, or the like.
- the invention also relates to means for the implementation process work.
- This process may be suitable, even if it is complicated to implement, when the sheath consists of two faces joined by their edges, but it can no longer be used when the two sides are joined by bellows because in this case cutting the shutter is very difficult to achieve.
- the method of the invention which overcomes these drawbacks, consists in fold the end of the sheath to be closed for the first time, apply a adhesive material, or glue, on the visible side of the folded down part and to be folded a second time said end so as to bring the glued side on that upper sheath.
- the problem to be solved consists of making bags from a tubular sheath, or sheath 1.
- This sheath has two faces 2 and 3 joined by bellows 4.
- the sheath 1 is wound in the form of a coil, it is then cut off, according to the length of the object to be wrapped and one of its ends is closed. It is the shutter of one of the extremities which is a problem.
- one of the ends of the sheath is folded back to form a flap 5
- an adhesive, or glue is deposited on the upper face 5a said flap then fold a second time and in the same direction the flap for apply its face 5a against the upper face 2 of the sleeve 1.
- FIG. 4 illustrates a machine allowing the implementation of the method of the invention.
- This machine comprises: a supply station 6, a station drive 7, a cutting station 8, a shaping station 9 and a training station 10.
- the supply station is of a known type and is intended to keep the sheath 1 wound in the form a coil 11.
- the training station 7 is constituted, in its simplest form, by two pressing cylinders 12, at least one of which is rotated, the sleeve 1 passing between said cylinders.
- the station 8 is provided with a cutting member, not shown, allowing to cut the sheath 1.
- the shaping station includes a folding member and, to the right of this body, a body 13 capable of carrying out the sizing.
- the folding member consists of two identical needles 14 and 15, parallel and extending transversely to the longitudinal axis of the sleeve 1, the distance separating the two needles being substantially equal to the width L of the part 5 to be carried out.
- These needles are carried, by one of their ends by a drum 16, rotary, whose axis of rotation extends parallel to the axes of said needles.
- the second training station 10 is constituted, like the first, by means of two pressing and driving rollers 12.
- the sheath 1 is engaged between the cylinders 12, passes through the member 14, passes between needles 14-15 and passes between cylinders 17.
- the drum moves transversely according to the arrow T, to allow the needles to be released.
- the needles move in the opposite direction and the cycle begins again for the shaping of a new bag.
- the obturation process of the invention allows, in fact, to apply after folding one of the external faces of the sheath against the other external face.
