Abstract
A machine for making, filling and sealing bags containing liquid, pulverulent, granular and other noncoherent materials, which is of the type having a vertical operating structure comprising structure for the formation and advancing of a continuous tube of heat-sealable material and also for feeding the product which is to be packed and for the longitudinal and transverse heat-sealing of the tube containing the product to be packed. In a machine of this kind the advancing structure and the transversal heat-sealing structure are associated with a support controlled by a mechanism belonging to the continuous motion kinematic structure, the advancing structure being formed by two sector members having cylindrical surfaces and contrarotating tangentially to a plane containing the axis of descent of the tube of heat-sealable material, while the mechanism comprises a cyclic differentiator device for the transmission of the motion.
