A machine for folding and adhesively bonding blanks for the production of folding boxes. It includes a transport system which has at least one puller which wraps around deflecting rollers and extends along a processing path, a drive connected to a deflecting roller and drives the deflecting roller. Workpiece carriers are fastened to the puller and are moved along the processing path by the at least one puller. It also includes a magazine for a stack of blanks, a mechanism for removing individual blanks from the stack in the magazine, a feeding mechanism for the removed blanks to the workpiece carriers, active means for retaining blanks on the workpiece carriers, control means, which are connected to the active means to control the retention and release of the blanks, and at least one means arranged on the processing path in a stationary manner for adhesively bonding blanks.

A presser assembly is provided for supporting a carton blank. The presser assembly includes a housing having a cavity formed therein. A presser plunger is telescopically received in the housing. The presser plunger is slidable between a first retracted position wherein the presser plunger is at least substantially received with the cavity in the housing and an extended position wherein the presser plunger projects from the open end of the housing. A magnetic biasing structure urges the presser plunger toward the extended position.

A box former may include a carton blank dispensing device that holds a carton blank and carton moving devices that move the carton blank from the carton blank dispensing device and positions it between a plunger and a forming well. The forming well may include a floor, one or more walls, and an opening. The plunger may be configured to move between a retracted position and one or more extended positions, the plunger contacting a top surface of the carton blank and pushing the carton blank into the forming well through the opening of the forming well. In some implementations, the box former may include forming guides that contact points on a bottom surface of the carton blank when it is pushed by the plunger to cause the carton blank to fold into a formed carton.

Provided herein is a machine for forming a container from a blank including a tray and a lid. The machine has an upstream end where the blank is loaded and a downstream end where the container is discharged and includes a frame, a pre-forming assembly, and a mandrel assembly. The pre-forming assembly is configured to partially form the lid and the tray by folding each of a plurality of side panels of the blank and further form the tray by partially folding a front panel assembly of the blank, the front panel assembly including a front panel and a roll-over panel. The mandrel assembly is mounted to the frame and configured to engage a bottom panel of the tray to form each of a plurality of corners of the tray and fold the roll-over panel to form a front wall of the container.

A box folding machine includes a base driving member, a pair of positioning units, and a base frame unit that has two opposite end portions. The base driving member is operable to drive the base frame unit to move between a first position, in which the end portions of the base frame unit are substantially arranged along a first direction, and a second position, in which the end portions of the base frame unit are substantially arranged along a second direction. Each of the positioning units includes a positioning seat. When the base frame unit is in the first position, the positioning seats of the positioning units are proximate to each other in the second direction and are misaligned from each other. When the base frame unit is in the second position, the positioning seats are distal from each other in the second direction.

An apparatus and method for expanding a box blank into a box, the apparatus comprising an arm assembly, a controller, a camera and a box blank conveyor. The arm assembly includes a folding arm having a position in a first direction and a rotational angle controlled by the controller based on a position of a feature of the box blank in the field of view of the camera. The camera captures images of the box blank which are used to position the arm assembly and to evaluate the need to reject a box blank.

A magazine for packs of blanks includes a vertical channel configured for inserting and extracting packs of blanks, a succession of groups of supporting parts movable between a retracted position to allow the packs of blanks to move along the channel towards a portion under the supporting part, and an at least partly extracted position, in which the supporting part intercepts a pack of blanks moving down the channel and provides a steady support for the pack of blanks, and transmission means configured to automatically move each supporting part from the retracted position to the at least partly extracted position when the supporting part immediately below it intercepts a respective pack of blanks, thereby defining the steady support.

A presser assembly is provided for supporting a carton blank. The presser assembly includes a housing having a cavity formed therein. A presser plunger is telescopically received in the housing. The presser plunger is slidable between a first retracted position wherein the presser plunger is at least substantially received with the cavity in the housing and an extended position wherein the presser plunger projects from the open end of the housing. A magnetic biasing structure urges the presser plunger toward the extended position.
