Abstract
Abstract Apparatus for closing an article wrapper that has a lower tubular portion integrally formed with an upper flap. The apparatus includes a horizontally extending frame having an entrance section and a conveyor section with the former having a rail for maintaining the flap spaced from the tubular portion as the wrapper moves toward the conveyor section. The conveyor section has a power-operated flap depressor that serves to move the lower edge of the flap into position for bonding engagement with the tubular portion while the wrapper is being moved by an endless belt towards the exit end of the apparatus.

Claim 1
Independent Claim
213 words
An apparatus for closing an article wrapper having a lower tubular portion integrally formed with an upper flap that terminates with a straight edge, said apparatus including an elongated frame divided into an entrance section and a conveyor section, said entrance section having means for supporting said article wrapper for movement towards said conveyor section while maintaining said flap spaced from said tubular portion, said conveyor section being axially aligned with said entrance section and having a power driven belt for moving said article wrapper along said conveyor section, means carried by said conveyor section for applying adhesive to said tubular portion as said article wrapper moves into said conveyor section, a positioner member located adjacent said conveyor section for receiving the flap of said article wrapper and for guiding the flap into contact with said tubular portion after the adhesive is applied thereto, said positioner member having a flat floor, means for engaging said flap and for maintaining the straight edge thereof in contact with said flat floor prior to the flap contacting said tubular portion, and said conveyor section having means formed therewith for maintaining said flap in contact with said tubular portion to assure that said adhesive is substantially cured so that said flap is bonded to said tubular portion.

An apparatus for closing an article wrapper having a lower tubular portion integrally formed with an upper flap that terminates with a straight edge, said apparatus including an elongated frame divided into an entrance section and a conveyor section, said entrance section having means for supporting said article wrapper for movement towards said conveyor section while maintaining said flap spaced from said tubular portion, said conveyor section being axially aligned with said entrance section and having a power driven belt for moving said article wrapper along said conveyor section, means carried by said conveyor section for applying adhesive to said tubular portion as said article wrapper moves into said conveyor section, a positioner member located adjacent said conveyor section for receiving the flap of said article wrapper and for guiding the flap into contact with said tubular portion after the adhesive is applied thereto, said positioner member having a flat floor, means for engaging said flap and for maintaining the straight edge thereof in contact with said flat floor prior to the flap contacting said tubular portion, and said conveyor section having means formed therewith for maintaining said flap in contact with said tubular portion to assure that said adhesive is substantially cured so that said flap is bonded to said tubular portion.
Claim 3
Independent Claim
229 words
An apparatus for closing an article wrapper having a lower tubular portion integrally formed with an upper flap that terminates with a straight edge, said apparatus including an elongated frame divided into an entrance section and a conveyor section, said entrance section having roller means for supporting said article wrapper for horizontal movement towards said conveyor section, an elongated rail attached to said entrance section for maintaining said flap spaced from said tubular portion, said conveyor section being horizontally aligned with said entrance section and having a power driven endless belt for moving said article wrapper along said conveyor section, means carried by said conveyor section for applying adhesive to said tubular portion as said article wrapper moves into said conveyor section, a positioner member located adjacent said conveyor section for receiving the flap of said article wrapper and for guiding the flap into contact with said tubular portion after the adhesive is applied thereto, said positioner member having a flat floor, means for depressing the upper portion of said flap so as to maintain the straight edge thereof in contact with said flat floor prior to the flap contacting said tubular portion, and said conveyor section having means formed therewith for pressing said flap into contact with said tubular portion to assure that said adhesive is substantially cured so that said flap is bonded to said tubular portion.
