Abstract
Abstract Apparatus for erecting cartons from a flattened condition thereof including a conveyer for moving flattened cartons at regular intervals; structure for directing a blast of air at a pressure greater than ambient against an end of the carton to partially erect the same while being conveyed; structure opposing the air blast; structure in spaced relationship to the conveyor and in increasing spaced relationship thereto to accommodate the erecting movement and to prevent dislodgement of the partly erected blank by the air blast; and structure for trapping and removing the erected carton.

Total Claims: 14
Claim 1
Independent Claim
220 words
In a machine for erecting carton sleeves from a flattened condition thereof: a. first endless conveyer means for moving flattened individual cartons at regular intervals by engagement of a carton at a trailing edge thereof; b. plenum means extending along one side of said first conveyer means with an opening therein directed against the end of a carton sleeve for applying a blast of air under pressure greater than ambient to partially erect said carton sleeve while the same is conveyed along said conveying means; c. said plenum means having a dimension along said conveyer means at least equal to the dimension of said carton sleeve in the flattened condition thereof; d. means extending along an opposite side of said first conveyer means and disposed with reference to an opposite end of said carton sleeve in opposition to said blast of air to minimize loss of pressure above ambient of said blast therewithin; e. means extending in increasing spaced relation to the conveyer means to accommodate the erecting movement of said cartons as they are conveyed along said first conveyer means and to prevent dislodgement of individual partly erected cartons from said first conveyor means by said blast of air; f. other means including regularly spaced means thereon to trap an erected carton sleeve therebetween to complete the erection thereof.
Claim 2
Dependent Claim

In a machine for erecting carton sleeves from a flattened condition thereof: a. first endless conveyer means for moving flattened individual cartons at regular intervals by engagement of a carton at a trailing edge thereof; b. plenum means extending along one side of said first conveyer means with an opening therein directed against the end of a carton sleeve for applying a blast of air under pressure greater than ambient to partially erect said carton sleeve while the same is conveyed along said conveying means; c. said plenum means having a dimension along said conveyer means at least equal to the dimension of said carton sleeve in the flattened condition thereof; d. means extending along an opposite side of said first conveyer means and disposed with reference to an opposite end of said carton sleeve in opposition to said blast of air to minimize loss of pressure above ambient of said blast therewithin; e. means extending in increasing spaced relation to the conveyer means to accommodate the erecting movement of said cartons as they are conveyed along said first conveyer means and to prevent dislodgement of individual partly erected cartons from said first conveyor means by said blast of air; f. other means including regularly spaced means thereon to trap an erected carton sleeve therebetween to complete the erection thereof.
Claim 3
Dependent Claim
58 words
A machine according to claim 1 wherein said first conveyer means is provided with carton engaging lugs having a pitch distance greater than the combined width of a main panel and a side panel of said carton sleeve, and wherein said other means includes trapping lugs having a pitch distance equal to the width of a main panel.
Claim 4
Dependent Claim
31 words
A machine according to claim 2 wherein said trapping lugs extend along the side panels of the erected carton sleeve to maintain the erected carton sleeve with a rectangular cross section.
Claim 5
Dependent Claim
35 words
A machine according to claim 1 wherein said other means includes a second conveyer having an orbitally movable strand, and wherein the means thereon includes trapping lugs engaging side walls of an erected carton sleeve.
Claim 6
Dependent Claim
58 words
A machine according to claim 1 wherein said first endless conveyer means and said other means move along a conveying reach, and wherein said first conveyer means is provided with regularly spaced carton sleeve engaging lugs thereon which move out of the plane of said reach as said other means enGages a carton sleeve for erecting movement thereby.
Claim 7
Dependent Claim
38 words
A machine according to claim 1 wherein the means extending along the opposite side of said conveyer means includes an abutment plate contacting the opposite end of said carton to trap air therein to erect said carton sleeve.
Claim 8
Dependent Claim
194 words
In a conveyer for erecting cartons from a flattened condition thereof: a. first endless conveyer means for moving flattened individual cartons at regular intervals by engagement of a carton at a trailing edge thereof; b. means disposed to one side of said first conveyer means with an opening therein directed against the end of a carton for applying a blast of air under pressure greater than ambient to partially erect said carton while the same is conveyed along said conveying means; c. means extending along an opposite side of said first conveyer means and disposed wIth reference to an Opposite end of said carton in opposition to said blast of air to minimize loss of pressure above ambient of said blast within said carton; d. means extending along said conveyer means in increasing spaced relationship to the conveyer means to accommodate the erecting movement of said cartons as they are conveyed along said first conveyer means and to prevent dislodgement of individual partly erected cartons from said first conveyer means by said blast of air; e. other means including regularly spaced means thereon to trap an erected carton therebetween to complete the erection thereof.
Claim 9
Dependent Claim
194 words
In a conveyer for erecting cartons from a flattened condition thereof: a. first endless conveyer means for moving flattened individual cartons at regular intervals by engagement of a carton at a trailing edge thereof; b. means disposed to one side of said first conveyer means with an opening therein directed against the end of a carton for applying a blast of air under pressure greater than ambient to partially erect said carton while the same is conveyed along said conveying means; c. means extending along an opposite side of said first conveyer means and disposed wIth reference to an Opposite end of said carton in opposition to said blast of air to minimize loss of pressure above ambient of said blast within said carton; d. means extending along said conveyer means in increasing spaced relationship to the conveyer means to accommodate the erecting movement of said cartons as they are conveyed along said first conveyer means and to prevent dislodgement of individual partly erected cartons from said first conveyer means by said blast of air; e. other means including regularly spaced means thereon to trap an erected carton therebetween to complete the erection thereof.
Claim 10
Dependent Claim
57 words
A machine according to claim 7 wherein said first conveyer means iS provided with carton engaging lugs having a pitch distance greater than the combined width of a main panel and a side panel of said carton, and wherein said other means includes trapping lugs having a pitch distance equal to the width of a main panel.
Claim 11
Dependent Claim
29 words
A machine according to claim 8 wherein said trapping lugs extend along the side panels of the erected carton to maintain the erected carton with a rectangular cross section.
Claim 12
Dependent Claim
34 words
A machine according to claim 7 wherein said other means includes a second conveyer having an orbitally movable strand, and wherein the means thereon includes trapping lugs engaging side walls of an erected carton.
Claim 13
Dependent Claim
56 words
A machine according to claim 10 wherein said first endless conveyer means and said other means move along a conveying reach, and wherein said first conveyer means is provided with regularly spaced carton engaging lugs thereon which move out of the plane of said reach as said other means engages a carton for erected movement thereby.
Claim 14
Dependent Claim
37 words
A machine according to claim 7 wherein the means extending along the opposite side of said conveyer means includes an abutment plate contacting the opposite end of said carton to trap air therein to erect said carton.
