A vertical bag-making/filling/packaging machine (1) comprises: a film supplying portion (5) which lets out a film (F) from a roll (Fr); a bag-making guide (31) which folds the film (F) into a tubular shape and changes a conveying direction downward; a vertical sealing portion (60) which thermally seals side edges of the film (F) to each other in an up-down direction so as to make the film into a tubular shape; a film conveying portion (50) which conveys the film (F) downward; a filling portion (70) which loads a content (X) into an interior of the film (F); a lateral sealing portion (80) which thermally seals the film (F) in a left-right direction so as to make a bag body; a square-bottom sealing portion (90) which expands a bottom of the bag body to a rectangular shape from an inside and then thermally seals the bottom to form a rectangular bottom surface; and a cutter (89) which cuts off the bag body from the film (F).

An erecting aid for packaging materials is described and may include a table portion and a panel. A panel may be coupled to one side of the table portion. The table portion and the panel can be configured such that the table portion and panel form an acute angle and the panel acts as a type of back support wall with respect to the table portion. A clamp may cooperate with the table portion to produce a clamping force. The clamping force may occur by biasing at least a portion of the clamp towards a relaxed, closed. The combination of the table, panel and biased clamp provide the forces necessary to stabilize a partially folded corrugated box during the erecting process such that the partially folded corrugated box is stabilized and maintained in a partially assembled state while the operator can use both hands to complete the erecting process.

A box packing apparatus is equipped with a first conveyor, a parallel link robot, and a flap folding mechanism. The first conveyor conveys an article. The parallel link robot takes hold of the article on the first conveyor and carries it into a cardboard box that has an upper opening. The flap folding mechanism folds open to the outside of the upper opening at least one of plural cover flaps of the cardboard box that are located around the upper opening.

Apparatus for extracting stacked articles from cardboard containers includes a store receiving the containers with a bottom closed by a tab; a rest and sliding plane substantially vertical and transversal to the store; a channel in a second unloading position, distant from the first pick-up position, for unloading the articles in the containers; abutting and folding means, lateral to the store near the first pick-up position for abutting and folding about the tab and opening the bottoms of the containers; an abutting plane substantially horizontal and transversal to the rest and sliding plane and lateral to the store between the first pick-up position and the unloading channel, to retain the articles inside the containers once the bottoms are open, and having an opening at the inlet of the unloading channel.

For the purpose of erecting and filling a folding box which has closure flaps on two opposite sides, the folding box is removed from a store and erected such that the closure flaps are arranged on its upper side and its underside. The lower closure flaps are folded over and the underside of the folding box is thus closed, whereupon products are introduced into the folding box. Then, the upper closure flaps are folded over, as a result of which the upper side of the folding box is closed. Thereafter, both the upper closure flaps and the lower closure flaps are fixed in their closed position in a downstream fixing apparatus.

According to the invention, the device comprises at least one flap spreading head (12a, 12b), the flap spreading head being vertically mobile for insertion thereof into a container (3) to be processed and including first and second flap spreading blades (121.sub.1, 121.sub.2) mounted on pivots and an actuator (122.sub.1, 122.sub.2). The actuator is adapted to command rotation of the flap spreading blades that on rotating come into contact with flaps (R1a, R1b) and bring about spreading thereof by folds toward the exterior of the container.
