Abstract
Abstract In an apparatus for forming bundles of flattened bags and successively transporting said bundles away, a rotary cylinder deposits successive bags edgewise on a depositing table disposed between the cylinder and a stationary support. The bags are accumulated in juxtaposition on the table to form a stack and gripper means periodically withdraw a bundle of bags from the stack by passing through the table between the cylinder and the support. The gripper means are non-coterminous with the space between the cylinder and the support so that they withdraw a bundle containing fewer bags than are contained in the stack.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
169 words
Apparatus for forming bundles of flattened bags and successively transporting said bundles away, comprising a depositing table; a rotary depositing cylinder effective to deposit successive said bags edgewise on the depositing table, said table being disposed substantially radially with respect to said cylinder; resilient holding means for resiliently holding said deposited bags in juxtaposition substantially perpendicular to said table to form a stack and disposed laterally of said table and axially of said cylinder; and gripper means for separating a bundle from said stack of juxtaposed bags from said table and for lifting said separated bundle from said table, said gripper means being adapted to pass through a portion of said stack and said depositing table in a direction opposite to the direction of rotation of said cylinder so that said bundle of bags lifted thereby contains only part of said stack of juxtaposed bags on said depositing table, the length of said gripper means being adjustable to vary the size of said bundle lifted by said gripping means.
Claim 2
Dependent Claim
169 words
Apparatus for forming bundles of flattened bags and successively transporting said bundles away, comprising a depositing table; a rotary depositing cylinder effective to deposit successive said bags edgewise on the depositing table, said table being disposed substantially radially with respect to said cylinder; resilient holding means for resiliently holding said deposited bags in juxtaposition substantially perpendicular to said table to form a stack and disposed laterally of said table and axially of said cylinder; and gripper means for separating a bundle from said stack of juxtaposed bags from said table and for lifting said separated bundle from said table, said gripper means being adapted to pass through a portion of said stack and said depositing table in a direction opposite to the direction of rotation of said cylinder so that said bundle of bags lifted thereby contains only part of said stack of juxtaposed bags on said depositing table, the length of said gripper means being adjustable to vary the size of said bundle lifted by said gripping means.
Claim 3
Dependent Claim
13 words
The apparatus defined in claim 1, wherein said resilient holding means comprise brushes.
Claim 4
Dependent Claim
23 words
The apparatus as defined in claim 1, wherein said gripper means comprises a swing arm carrying a flanged triangular blade at its end.
