Abstract: The present invention relates to a basket carrier that provides full protection for the bottles being carried, and which can be glued on a straight-line gluer. The provision of nicks (i.e., temporary bridges) between the handle panels and the side walls serves to keep the handle panels in proper alignment during the folding and gluing operation on the gluer. These nicks are easily broken when the carrier is opened to receive bottles in the bottling plant. The present invention also utilizes nicks between the partition panel and the handle ply to hold them in contact but yet prevent bunching of paperboard during the folding and gluing process.

Abstract: This invention relates to carriers that have partition panels attached to one or both ends of the carrier via an end flap. All of the outside panels of these carriers are folded about lines that are parallel to the longitudinal direction of the gluer on which the carrier is folded and glued. All of these carriers have multi-ply handles in which none of the plies are foldably attached to each other at their top edges. Nicks may be provided between the handle panels and the side and end flaps to hold the carrier in proper position during the folding and gluing operation. This invention also relates to a method of folding and gluing the carriers on a straight-line gluer.

Abstract: A basket-style carrier which includes a top panel. The end panels are comprised of two separate sections, each of which is connected to a center panel, and are spaced from the top panel. The top panel is foldably connected to the side panels and includes a handle. Vertical folds in the end panels allow the end panels to follow the contour of adjacent packaged bottles. In three embodiments the top panel includes bottle neck openings. In a fourth embodiment partial upper end panels connected to the top panel are spaced from the lower end panels. Gusset panels connected to upper end panel flaps and to glue flaps connected to the side panels automatically cause the upper end panel elements to fold into place during the carrier forming operation.

Abstract: A carton feeder for a continuous motion packaging machine includes a speed compensation controller and a solenoid dual valve assembly, which enable the feeder to operate at higher speeds. The dual valve assembly includes a vacuum valve coupled to an air pressure valve which is controlled by an electronic controller. The speed compensation assembly is electronically connected to the valve controller, and includes an encoder driven by the feeder and a programmable limit switch for receiving data from the encoder and transmitting control signals to the valve controller. The method of operation includes detecting the position of the selector and transmitting position data to the limit switch. The limit switch calculates optimum valve actuation timing based upon both programmed information and data from the encoder, and transmits the control signals to the valve controller.
