US 6,830,241 B1 · Pocket assembly forming different size assemblages

Abstract

An apparatus for use in forming sheet material assemblages includes a pocket assembly having upper and lower grippers. The upper gripper is spaced a first distance from a sheet material support portion of the pocket assembly to engage an upper edge portion of a large cover section having a relatively large distance between a fold and an upper edge portion. The lower gripper is spaced a distance which is smaller than the first distance from the sheet material support portion of the pocket assembly to engage an upper edge portion of a small cover section having a relatively small distance between a fold and an upper edge portion of the cover section. Pressers are mounted on a movable side wall of the pocket assembly and are engagable with a side of a small cover section to press small the cover section toward the lower gripper.

Dependent claims

An apparatus for use in forming sheet material assemblages which include a folded cover section having two sides and into which other sheet material items are inserted, said apparatus comprising;

a pocket assembly which is sequentially movable past a folded cover section feeder and a plurality of sheet material item feeders,
said pocket assembly including forward and rear walls defining a pocket into which a folded cover section is fed and a mechanism for opening folded cover sections of different sizes to receive sheet material items fed by the sheet material item feeders;
said mechanism for opening folded cover sections of different sizes comprising a first gripper for gripping one side of a folded cover section of one size, and a second gripper spaced apart from said first gripper for gripping one side of a folded cover section of a different size, said first gripper being ineffective to grip said folded cover section of a different size, said second gripper being ineffective to grip said folded cover section of one size.

An apparatus for use in forming sheet material assemblages of different sizes, said apparatus comprising:

a pocket assembly which is sequentially movable past a plurality of sheet material feeders, said pocket assembly including a base and a sheet material support portion which is connected with said base and is engagable with a folded portion of a cover section of a sheet material assemblage with opposite sides of the cover section extending upward from the folded portion of the cover section,
a first gripper connected with said base and spaced a first distance from said sheet material support portion to engage an upper edge portion of one side of a cover section of a first sheet material assemblage having a relatively large distance between a folded portion and an upper edge portion of the cover section of the first sheet material assemblage, and
a second gripper connected with said base and spaced a second distance from said sheet material support portion to engage an upper edge portion of one side of a cover section of a second sheet material assemblage having a relatively small distance between a folded portion and an upper edge portion of the cover section of the second sheet material assemblage, said first distance being greater than said second distance.

An apparatus for use in forming sheet material assemblages of different sizes, said apparatus comprising:

a pocket assembly which is sequentially movable past a plurality of sheet material feeders, said pocket assembly includes a base,
a first gripper connected with said base to engage an upper edge portion of one side of a cover section of a first sheet material assemblage,
a second gripper connected with said base to engage an upper edge portion of one side of a cover section of a second sheet material assemblage, said cover section for said first sheet material assemblage being larger than said cover section for said second sheet material assemblage, said pocket assembly includes a side section which is movable relative to said base to operate said pocket assembly between open and closed conditions, and
a presser which is movable with said side section relative to said base, said presser being engagable with the cover section of said second sheet material assemblage to press the cover section of said second sheet material assemblage against said base.
