Abstract
Abstract Apparatus for producing a folded tubular box from a box blank is provided with power driven means for adjusting the folding elements to operate on different size box panels. As the tubular boxes are produced, they are underfed into a stack and periodically a pile of boxes at the top of the stack is removed. While the boxes are in the stack, a hold-down means provides a downward force on the glue joint region connecting the inwardly folded panels of the box. A cable system interconnects the holddown means with the power driven means for adjusting the folding sections so that as the apparatus is adjusted for different size boxes, the hold-down means is automatically positioned to apply a downward pressure at the joint region.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
233 words
In box making apparatus the combination comprising a first section for transforming box blanks into folded tubular boxes and a second section for forming boxes received from said first section into a stack and periodically removing piles of boxes from the stack; said first section including conveyor means for moving blanks and folded tubular boxes along a feed path extending parallel to a reference line; said first section also including first and second folding portions on opposite sides of said reference line for inwardly folding respective first and second outboard panels of box blanks along first and second score lines thereof to positions where the outboard edges of said blank are in juxtaposition at a joint area; said first and second score lines being parallel to said reference line and being spaced therefrom by first and second distances, respectively; said second section including a hold-down means for applying downward pressure to the stack at the joint region; first and second adjusting means for positioning the respective first and second folding portions transversely in relation to said reference line in accordance with the respective first and second distances; and a cable system connecting both of said folding portions to said hold-down means to move the latter transverse to said reference line to automatically maintain said hold-down means at said joint area as said joint region shifts with changes in said first and second distances.
Claim 2
Dependent Claim
233 words
In box making apparatus the combination comprising a first section for transforming box blanks into folded tubular boxes and a second section for forming boxes received from said first section into a stack and periodically removing piles of boxes from the stack; said first section including conveyor means for moving blanks and folded tubular boxes along a feed path extending parallel to a reference line; said first section also including first and second folding portions on opposite sides of said reference line for inwardly folding respective first and second outboard panels of box blanks along first and second score lines thereof to positions where the outboard edges of said blank are in juxtaposition at a joint area; said first and second score lines being parallel to said reference line and being spaced therefrom by first and second distances, respectively; said second section including a hold-down means for applying downward pressure to the stack at the joint region; first and second adjusting means for positioning the respective first and second folding portions transversely in relation to said reference line in accordance with the respective first and second distances; and a cable system connecting both of said folding portions to said hold-down means to move the latter transverse to said reference line to automatically maintain said hold-down means at said joint area as said joint region shifts with changes in said first and second distances.
Claim 3
Dependent Claim
32 words
The combination as set forth in claim 1, in which the joint area is spaced from said reference line by a third distance equal to said first distance minus said second distance.
Claim 4
Dependent Claim
33 words
The combination as set forth in claim 2, in which the first distance is larger than said second distance and the joint region is between said reference line and said first score line.
Claim 5
Dependent Claim
145 words
The combination as set forth in claim 1 in which the cable system includes a first drive cable anchored to said hold-down means and said first folding portion, a first fixed guide for said first drive cable secured to a first stationary area outboard of said first folding portion, a first movable guide for said first drive cable, a second drive cable anchored to said hold-down means and said second folding portion, a second fixed guide for said second drive cable secured to a second stationary area outboard of said second folding portion, a second movable guide for said second drive cable, a first guide cable supporting said first movable guide and anchored to said second folding portion and said second stationary area, and a second guide cable supporting said second movable guide and anchored to said first folding portion and said first stationary area.
Claim 6
Dependent Claim
40 words
The combination as set forth in claim 4 in which the first folding portion is disposed between the hold-down means and the first stationary area, said second folding portion being disposed between the hold-down means and the second stationary area.
Claim 7
Dependent Claim
40 words
The combination as set forth in claim 5 in which the first movable guide is positioned between the hold-down means and the first folding portion, said second movable guide being positioned between the hoLd-down means and the second folding portion.
Claim 8
Dependent Claim
32 words
The combination as set forth in claim 6, in which the joint area is spaced from said reference line by a third distance equal to said first distance minus said second distance.
Claim 9
Dependent Claim
33 words
The combination as set forth in claim 7, in which the first distance is larger than said second distance and the joint region is between said reference line and said first score line.
