Latest Patents
One of Hisamitsu Ishihara's latest patents is a film cutting device. This device features a fixed cutter on the top surface of an adsorption type carrying belt that transports a film. A cylindrical cutter holder with a rotary cutter is positioned near the fixed cutter. The fixed cutter has a nearly triangular cross-section, which includes an inclined surface that guides the film to the blade edge. The rotary cutter's blade edge is offset, allowing the film to be cut through the relative operation of both blade edges during the rotary cutter's rotation. Both cutters are installed in a cutter unit, which is fixed to a frame part of a packaging machine, enabling positional adjustments.
Another significant patent is for a bag-making-and-filling packaging apparatus. This invention enhances the process where a web from a roll of packaging material is formed into a tube. The formed tube is intermittently delivered and filled with the material to be packaged. Once filling is complete, the tube is sealed along its width. The apparatus includes an improved packaging material delivery device that ensures durability and prevents damage to the packaging material, resulting in a better packaging finish. Additionally, it features an improved registering device that simplifies the setting and adjusting operations associated with a register mark sensor.
