Abstract: A modified glue flap of a folding carton blank for preventing glue from being squeezed out during the step of adhering the glue flap to the opposite end panel. The face of the glue flap engaged by the glue back-up wheel includes a protrusion near the trailing edge of the flap. Engagement of the protrusion by the back-up wheel causes the glue wheel to skip the trailing area of the flap. The absence of glue in this area prevents glue from being squeezed out when sealing pressure is subsequently applied to the glue flap and the opposite end panel. The protrusion may take the form of an embossed ridge, forming a channel on the opposite side of the protrusion for receiving any excess glue which would have been squeezed out.

Abstract: The invention relates to a multiple pot comprising individual pots interconnected by connector portions so as to be capable of being pulled out. The multiple pot is used to raise and transplant seedlings of plants. The invention also relates to a method of fabricating the pot. The pot is designed especially to promote growth of roots across the side walls of the individual pots after transplantation. Also, the resistance encountered when the multiple pot is unfolded is reduced. Further, the individual pots are uniform in size. These feature arise from the facts that the connector portions are formed by applying a waterproof paste discontinuously and that a water-soluble paste is not applied around the edges of the individual pots created when the multiple pot is unfolded. Hence, a coating of the paste is formed in none of these portions. The multiple pot is fabricated by continuously carrying out three steps.

Abstract: The invention relates to a method for blowing away particles of glue in a strip-gluing unit for folding box forming machines for gluing box blanks. Compressed air is blown from the side of a gluing disc of the gluing unit at an acute angle obliquely towards the direction of travel of the blank at the height of the nip between the blank and gluing disc so that on account of the high speed of the blanks and gluing disc, particles of glue which are thrown off are removed on the shortest path, without these particles splashing on the blanks and machine parts. The air is blown by an air-guide member, which comprises an air chamber, which is connected by lines to a source of compressed air. Starting from the air chamber is a bore whose axis is directed at the height of a nip at the acute angle. The air-guide member is attached in the folding box sticking machine independently of the gluing unit and is seated laterally beside the gluing disc and serves simultaneously to support the travelling blanks.

Abstract: The horizontally extending cover side flaps of a plurality of identical filled closed cartons, are glued, down folded, pressed and set by continuously advancing the cartons individually and successively, in untimed relation, between upper and lower carrier belts and along a path through an adhesive applying zone, a flap folding zone and a compression zone. The upper carrier belts are mounted on a sub-frame structure as are the gently curved down fold bars and are raised and lowered relative to the main frame for runs of different height cartons. The glue pots are independently movable vertically and laterally. The compression rolls are resiliently and yieldably mounted to individually and successively press and set the hot melt adhesive without undue pressure which might retard the untimed advance of the cartons.
