Abstract

PURPOSE: To provide a method, wherein a bag can be opened and at the same time can be clamped by simply swinging bow-shaped swingable members.
CONSTITUTION: Each pair of grippers 11, 12 grip each upper corner of a flatened bag 15 having an opening 21 in the upper portion thereof which has been delivered from a preceding station. A pair of swingable members 1, 1' having respective fulcrum 2, 2' above the grippers are swung in the same plane as that of the bag so that the members 1, 1' may be moved in opposite directions with respect to each other, and ends, crests, sides and bottoms of the bow-shaped members 1, 1' cooperate to spread away the flatened opening 21. A carriage unit A comprises a carriage frame 3 having guide rolls 13 and press rolls 14. While the unit A is being moved toward the left, a cylinder 4 is actuated to swing the members 1, 1' to the left and right, respectively, through links 5, 5' and levers 6, 6' so that ends 1a, 1a' may be inserted into the opening 21 to spread it.
