ABSTRACT:
A bag-making apparatus which comprises a support table carrying a bag material which is put thereon, a pair of side guides being provided above the support table, being movable in the direction perpendicular to the traveling direction of the bag material and controlling both side of the bag material, a pair of top guides being movable in the direction perpendicular to the traveling direction of the bag material together with the side guides, having the space therebetween gradually narrower from the approach side to the leaving side of the bag material, and controlling the front face of the bag material made tubular, and forming rollers being disposed on the approach side of the bag material from the top guides, being movable in the direction perpendicular to the traveling direction of the bag material, and pressing the bag material onto the support table. The bag-making apparatus can change the bag width rapidly and accurately in a simple action without stopping the travel of the bag material resulting to shorter the working time and to improve productive efficiency. The loss of the bag material due to the bag width changes can be reduced.
