Abstract (en)
[origin: EP0142456A2] 1. Process for forming the bottom of a sachet of flexible synthetic material from a cushion (1) of synthetic material filled with liquid, and for imparting stability to it, in which the filled cushion (1) is disposed on a support beam (6) of width less than the width of the cushion in such manner that at least one of the lower corners (7, 8) of the cushion protrudes beyond the beam, tending downwards, characterised in that a gripper (9, 10) is applied to each side of the beam, the exerted pressure force of which gripper expelsthe liquid contained in the said corner or corners, in that welding is effected along at least one line which will impart stability to the sachet, thus forming at least one lug, each corresponding to a corner (7, 8).
