A machine for mechanically opening and emptying bags which may contain a toxic product, comprising:
- (a) a conveyor arranged to bring bags placed on it to a hopper for collecting the products contained in the bags,
- (b) severing means adapted for severing the front face and the two lateral faces of a bag carried by the conveyor during the advancement of the latter, without severing totally the back face of the bag, and
- (c) pivoting arms disposed for pivotal movement about a fixed axis, said pivotal arms having a gripping means affixed thereto, said pivotal arms being movable between a first position wherein said gripping means grips a top portion of said severed bag when said bag is full, and a second position wherein said bag is detached after being emptied, the movement of said pivotal arms from said first position to said second position spreading said severed bag to an amount approximating two times the length of said bag, while said bag is supported upon said conveyor, said bag remaining supported by said conveyor as the products contained in said bag are emptied into said hopper.
