Abstract: Machine 2 and associated method for making a bag bottom “B” starts from a single tube-shaped sheet “F”. The machine includes: at least one opening element 21 for spreading apart the tube-shaped sheet “F”, which is positioned between a first portion “s1” and a second portion “s2” of the sheet “F”. At least one actuating device 3 moves the first portion “s1”. The machine further includes at least one first striker element 22 for defining a first folding point for making a first side “l1” of the bag bottom “B” after the first portion “s1” has been moved, and at least one second striker element 23, inclined by an angle “a” relative to the first element 22, for defining a second folding point for making a second side “l2” of the bag bottom “B” after the first portion “s1” has been moved.

Abstract: An apparatus for finishing products coming out from a folding and gluing machine of cardboard or paperboard products with a back, includes a longitudinal housing for advancing the products in rows, defined by two groups (40, 41) of circular motorized right and left belts. Each group (40, 41) being made of at least three belts. An upper belt (22, 24) and a lower belt (25, 27) are wrapped around pulleys with a horizontal axis and extending parallel to the direction of advancement of the products. A lateral belt (28, 29) is wrapped around pulleys with a vertical axis and extending parallel to the direction of advancement of the products. The belts of each group (40, 41) form among them respective “C”-shaped housing which make the lateral edges of the housing along and inside which the product advances, dragged by the belts.
