This invention relates to a transverse sealing mechanism for use in producing bag-packed products by packing products in tubular film. The transverse sealing mechanism comprises compression-and-heat sealing means and compression-cooling and compression-cutting means disposed immediately below said sealing means, each of these means having a mechanism which can increase its compressive force infinitely. The packed bag transverse sealing mechanism provides for storing and perfect seals.

Packed bag transverse sealing mechanism

The invention is a mechanism for regulating the speed and stroke of a transverse sealing means for a vertical packing machine using tubular film. The mechanism comprises a cranking disc, and elongated transverse rod and a vertical rod, these members being connected adjustably to each other to regulate the movement of the transverse sealing means.

Movement-regulating mechanism for a sealing device

A low-to-high pressure, fusion-welding, press mechanism for vertical packing machines which seals packed products using packing film. The press mechanism comprises a cylinder, a cylinder rod, a circular disc, a plurality of pairs of levers and a pair of sealing substrates having a pair of sealing blades, these members being interconnected to each other to fusion-weld packed products with said pair of sealing blades under desired sealing pressure.

Sealing mechanism for a packing machine

The invention provides an apparatus for transversely stretching a film tube at a portion to be transversely sealed and preventing creases from occurring in the transversely sealed portion of the film tube when a product fed in the film tube is separated by a squeeze roll means into a specified amount for one pack and thereafter the film tube is transversely sealed. Butterfly arms which pivotally spread apart in a fan-like manner are used for the stretching means.
