Abstract
Abstract An apparatus comprises a first feeding station for transferring a container blank to a main conveyer for movement along a linear path. The blank is conveyed to an adhesive application station wherein glue applicators are pivoted into contact with selected portions thereof. A second feeding station transfers a collar blank to a secondary conveyer for movement toward the container blank. A combining station then functions to accelerate and precisely position the collar blank on the container blank. The combined blanks then pass through a compression station to secure them together.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
252 words
An apparatus for securing first and second flat blanks together comprising a first blank feeding station, an adhesive application station, a second blank feeding station, a combining station and a compression station, said first blank feeding station comprising first feeding means for removing a first blank from a stack of blanks and for moving said first blank along a first linear path, first conveyor means for receiving said first blank from said first feeding means and for moving said first blank along said first linear path at a first linear speed, said adhesive application station comprising at least one application means for depositing a selected pattern of adhesive on said first blank, said second blank feeding station comprising second feeding means for removing a second blank from a stack of blanks and for moving said second blank along a second linear path disposed at an acute angle relative to said first linear path to intersect therewith, a second conveyer means for receiving said second blank from said second feeding means and for moving said second blank along said second linear path at a second linear speed which is less than the first linear speed of said first conveyer means, said combining station comprising registry means, having means for accelerating said second conveyer means and said second blank to a linear speed substantially equalling said first linear speed, for precisely positioning said second blank on said first blank, said compression station comprising means for receiving and compressing said first and second blanks together.
Claim 2
Independent Claim
252 words
An apparatus for securing first and second flat blanks together comprising a first blank feeding station, an adhesive application station, a second blank feeding station, a combining station and a compression station, said first blank feeding station comprising first feeding means for removing a first blank from a stack of blanks and for moving said first blank along a first linear path, first conveyor means for receiving said first blank from said first feeding means and for moving said first blank along said first linear path at a first linear speed, said adhesive application station comprising at least one application means for depositing a selected pattern of adhesive on said first blank, said second blank feeding station comprising second feeding means for removing a second blank from a stack of blanks and for moving said second blank along a second linear path disposed at an acute angle relative to said first linear path to intersect therewith, a second conveyer means for receiving said second blank from said second feeding means and for moving said second blank along said second linear path at a second linear speed which is less than the first linear speed of said first conveyer means, said combining station comprising registry means, having means for accelerating said second conveyer means and said second blank to a linear speed substantially equalling said first linear speed, for precisely positioning said second blank on said first blank, said compression station comprising means for receiving and compressing said first and second blanks together.
