  • This procedure according to the invention has the advantage that the resulting bag is still held in a more precisely defined position by the separating welding device and thus the blocking position can also be defined and the blocking can be carried out. Since the interlocking section is kept as small as possible for material and waste reasons, precise positioning is required. In addition, the interlocking weld must always be outside of the l Row of tear perforations.

Abstract

Paquets de sachets regroupés en bloc et procédé de production de ces paquets de sachets composés d'un film plastique avec des soudures latérales de séparation, un bord de transport approximativement sinusoïdal, des orifices d'accrochage ajourés et renforcés avec des feuilles de renforcement et des sections de regroupement en bloc formées d'un côté du sachet, détachables le long d'une ligne perforée, ce qui permet de détacher les sachets du paquet formé par la section de regroupement. Afin de fabriquer les sachets en paires, un film tubulaire aplati (1) est découpé en ligne droite ou sinusoïdale par son centre, et les deux demi-gaines (1a, 1b) ainsi obtenues sont déviées, échangeant leur chemin de transport de sorte que leur bord découpé (11) se trouvant initialement au centre du chemin de transport se retrouve du côté extérieur du chemin de transport. Des sections circulaires (6) sont séparées de la couche supérieure du film, partant du bord découpé ouvert, de façon à former sur la couche inférieure (10b) du film les sections (9) de regroupement en bloc.
