Method for altering the storage capacity of a tubular mesh bag

A method for altering the storage capacity of a tubular material during manufacture of a tubular bag, the method comprising:

• providing an expansion core having a free upstream end;
• passing the tubular material over the expansion core such that the tubular material is peripheral to the expansion core;
• providing an insertion mechanism for inserting sections of the tubular material into the expansion core as the tubular material passes over the expansion core;
• operating the insertion mechanism to insert sections of the tubular material into the expansion core such that a greater quantity of tubular material is accumulated per unit length in each longitudinal section of tubular material corresponding to one bag unit.
