Claim 4

Dependent Claim 66 words

A box forming apparatus for closing and taping the bottom of a box as defined in claim 1 wherein the means for folding the bottom flaps includes: a support frame; a folding body operably connected to said support frame which folds the back inner flap into the bottom opening plane of the box, said folding body being supported to enable it to rotate upward and downward.

Claim 5

Dependent Claim 230 words

A box forming apparatus for closing and taping the bottom of a box integrally formed with front and back inner flaps and right and left outer flaps, said box forming apparatus comprising: a box erecting frame; means operably connected to said box erecting frame for folding said front and back inner flaps and right and left outer flaps into a bottom opening plane of the box; means operably connected to said box erecting frame for preventing upward movement-of the box during a flap folding operation of said means for folding, said means for preventing upward movement positioned generally above said means for folding and operable to ascend and descend along a vertical axis and further comprising a body portion having at least one laterally extending shaft, said at least one shaft extending in a horizontal plane such that said at least one shaft abuts a portion of said box during a flap folding operation; means for securing the left and right outer flaps in a folded and closed position; said means for securing being adjacent to said means for preventing upward movement and including a tape head for applying a strip of tape along mating edges of the right and left outer flaps of said box; and means for conveying the box during a flap securing operation including a pair of side belts to catch and convey the box frame.

Claim 6

Dependent Claim 230 words

A box forming apparatus for closing and taping the bottom of a box integrally formed with front and back inner flaps and right and left outer flaps, said box forming apparatus comprising: a box erecting frame; means operably connected to said box erecting frame for folding said front and back inner flaps and right and left outer flaps into a bottom opening plane of the box; means operably connected to said box erecting frame for preventing upward movement-of the box during a flap folding operation of said means for folding, said means for preventing upward movement positioned generally above said means for folding and operable to ascend and descend along a vertical axis and further comprising a body portion having at least one laterally extending shaft, said at least one shaft extending in a horizontal plane such that said at least one shaft abuts a portion of said box during a flap folding operation; means for securing the left and right outer flaps in a folded and closed position; said means for securing being adjacent to said means for preventing upward movement and including a tape head for applying a strip of tape along mating edges of the right and left outer flaps of said box; and means for conveying the box during a flap securing operation including a pair of side belts to catch and convey the box frame.

Claim 7

Dependent Claim 126 words

A box forming apparatus as defined in claim 4 wherein the means for folding includes: a support frame; a conveyance means for moving the support frame between a first position wherein the support frame defines an outer periphery of a box flap folding zone and a second position opposed to the first position wherein the support frame is adjacent the means for securing; a flap folding member operably connected to a distal end of said support frame and mounted on a shaft such that said folding member rotates between a first position and a second folding position wherein said back inner flap is folded into the bottom opening plane of the box frame when said folding member rotates from said removed position to said folding position.

Claim 8

Dependent Claim 79 words

A box forming apparatus as defined in claim 5 wherein the means for folding includes: a pair of opposed folding arms journalled to rotate about an axis, each of said pair of folding arms including at least one roller whereby when said pair of opposed folding arms are caused to rotate, said rollers contact a respective left and right outer flap of said box frame and fold said flap to occupy a bottom opening plane of the box frame.

Claim 9

Dependent Claim 82 words

A box forming apparatus as defined in claim 4 wherein: said means for securing the left and right outer flap including a tape head frame, a tape dispensing means, and a tape cutting means; and a folding body secured to a distal portion of said tape head frame journalled to rotate about an axis such that said during a rotation of said body, a front inner flap of said box frame is guided into a bottom opening plane of the box frame.

Claim 10

Dependent Claim 94 words

A box forming apparatus as defined in claim 4 wherein: the means for preventing upward movement of the box frame during a flap folding operation by said means for folding comprises at least two shafts which extend through the body of the means for preventing upward movement and occupy a common horizontal plane and further comprising a plurality of roller elements journalled on said shafts wherein during a folding operation, upper right and left outer flaps of said box contact the roller elements which prevent movement of the box frame in an upward direction.

Claim 11

Dependent Claim 158 words

A box forming apparatus as defined in claim 4 further comprising: a box frame loading unit operably connected to said box forming frame comprising a pair of opposed entrance guides for guiding box frames which are in a flat folded state from a loading side of said entrance guides to an exit side of said entrance guides, said exit side of said entrance guides being located adjacent a box flap folding zone, said box frame loading unit further comprising at least a pair of vacuum suction pads operable between a first position at a periphery of said box flap folding zone and a second position adjacent said exit side of said entrance guides wherein said at least pair of vacuum pads grip a folded box located at said exit side when said vacuum pads are in said second position and convey said box into the box flap folding zone as said vacuum pads travel to said first position.
