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.
