Abstract
Abstract A bag making apparatus has a bonding means for making bonded seams between webs of thermoplastic material. The bonding means includes first (21 second (22), and optionally third (23), sets of cooperating rotary or reciprocating, bonding members for making transverse and longitudinal seams. The apparatus includes seaming interrupting means which cooperates with one of the bonding means. The bonding means and interrupting means are arranged to cooperate together to form bags from the webs of thermoplastic material so that each bag has a sealed or sealable compartment for containing or containing a material (48) for mixing, a pocket for measuring, and having a mouth opening (42) between the interrupted seams, and a frangible barrier between the compartment and the pocket.

Claim 10
Dependent Claim
107 words
A bag making apparatus incorporating bonding means comprising sets of cooperating rotary members for making bonded seams between moving webs of thermoplastics material, said sets including a first set for making seams longitudinally of the webs and a second set for making seams transversely of the webs, characterised in that the rotary bonding means includes seaming interrupting means which is arranged to operate in unison with one of the sets; and in that the sets and interrupting means are arranged to form bags from said webs, each bag comprising a sealed or sealable compartment, a measuring pocket and a frangible barrier between the compartment and the pocket.
Claim 11
Dependent Claim
107 words
A bag making apparatus incorporating bonding means comprising sets of cooperating rotary members for making bonded seams between moving webs of thermoplastics material, said sets including a first set for making seams longitudinally of the webs and a second set for making seams transversely of the webs, characterised in that the rotary bonding means includes seaming interrupting means which is arranged to operate in unison with one of the sets; and in that the sets and interrupting means are arranged to form bags from said webs, each bag comprising a sealed or sealable compartment, a measuring pocket and a frangible barrier between the compartment and the pocket.
