Abstract

The invention relates to manufacture of storage sacks made from tubular fabric and in particular to a device or an apparatus of and method for making multi-component sacks where packing sacks have an inner web inserted into them and joined together at the open end of the multi-component bag. In particular, the invention discloses a composite bags (C) made of an outer covering (1) and a liner insert (2) inserted into it are also termed as multi-component bags. The invention provides a process that allows the flexibility of joining the web liner insert along with the top edge of the outer covering to avoid separation of tapes at the edges. The invention also discloses an apparatus for making the composite bag and a process of making it.
