A cutting device of an integrated paper-plastic bag cutting and sealing machine includes a sliding bracket and a cutting knife. The sliding bracket is connected to a horizontal displacement driving mechanism. The sliding bracket is formed by connecting an upper plate with a rear plate. The sliding block is mounted on the rear plate through a connecting shaft and is capable of sliding back and forth along the connecting shaft, front and rear snapping grooves are arranged on the connecting shaft along the length direction. A cutting knife is mounted on the sliding block, its lowest position is lower than the bottom surface of the sliding block. A spring positioning column is mounted on the sliding block, the top end of the spring positioning column passes through the shaft hole wall of the connecting shaft of the sliding block and tightly presses against the connecting shaft.

The film sealing and wrapping machine with a rotary cut and seal jaw is provided. The rotary cut and seal jaw has an internal sliding mechanism which provides for smooth and quiet operation. The rotational speed of the jaw may be varied to increase through put and to provide for a title bag around products. The rotary cut and seal jaw may comprise a seal bar and pressure pad may both be spring loaded to self align the seal bar and pressure pad during the sealing and cutting process. Lastly, a gap defined by a belt disposed upstream and downstream of the seal bar and pressure pad may be mechanically linked to the pressure pad through a control carriage.

A method includes separating a portion of a flattened tube of stock packing material to a custom length to form a pouch pre-form and closing a first end of the pouch pre-form leaving a second end of the pouch pre-form open. The method can include placing product into the pouch pre-form and closing the one open end of the pouch pre-form to form a closed pouch containing the product.

Method, machine and installation for vacuum packaging of products, where a plurality of individual bags closed at one end and open at the opposite end with at least one product therein are generated. For generating the bags, a transverse cut and a complete transverse seal on both sides of the transverse cut are made on the film tube, and a transverse cut without complete transverse seals on the sides thereof is made at a distance (L) substantially equal to the desired length of the bag to be generated from the transverse cut and seal on both sides. Each bag is oriented at 180 degrees with respect to the bag previously generated in the forward movement direction.

A device for processing a continuous web includes a feed station for feeding the web in a feed direction towards a cutting station for cutting the web to a cutting length into individual segments of web that are disc-shaped. A further feed station feeds each segment. A first cutting unit cuts the web into the segments and a second cutting unit includes a cutting element configured to sever the web across a full width in a direction transverse to the feed direction. A drive unit is configured to issue a command to move the cutting element from a non-operating position, where the web is fed by the feed station to the first cutting unit through the second cutting unit, to an operating position, where the web is severed by the cutting element to interrupt feeding of the web to the first cutting unit.
