Flap folding device of a wrapping machine. Side folding guides approach side flaps to hit a hitting part against the closed side faces of a wrapped body part of a content or volume, thereby pressing a wrapped body part, near the base end of the side flaps that face the closed side faces, against the closed side faces. Subsequently, the middle part of each of the side folding guides makes a quarter turn while tracing a corner continued to the closed side faces,. Therefore, the base ends of the side flaps are folded along the corners while being pulled toward the forward end thereof, and, at the same time, are pressed by folding parts against the open sides, through the entire length, from the base end to the forward end, of the side flaps.

Flap folding device of wrapping machine

A packaging apparatus for applying a packaging sheet to cover the contents and simultaneously seal them including an adhering mechanism for adhering tape at corresponding sealing positions of the packaging sheet. The adhering mechanism is movable toward or away from the tape feeding-out mechanisms. Adhering tapes are adhered to the corresponding sealing position while being partially projected. The packaging sheet, including the adhering tapes, is fed out by the sheet feeding-out mechanism to the packaging start position. Concurrent to the completion of the folding of the packaging sheet during the packaging operation, projected portions of the adhering tapes are adhered.

Method for packaging contents and packaging device

A packaging apparatus that compresses the contents in a vertical direction and tightly winds the contents. Upon the lowering of the elevator, compressive receiving plates project above the contents. The elevator is raised to hold the contents between the compressive receiving plates and the contents are compressed in the vertical direction. The winding guides approach each other, while the contents are being compressed. Both ends of the packaging sheet are connected by the fixing elements, and then the compressive receiving plates are pulled out.

Packaging device

A method and apparatus for sealing and closing an end of a sleeve, more particularly an apparatus and method for bag making, filling, and packaging for intermittently delivering a packaging film of a predetermined length, while forming the film into a tubular shape by a bag making cylindrical body; filling the tubular packaging film with a material to be packaged; and clamping the tubular film by closing a pair of opposed sealing devices to heat seal the tubular film. Apparatus is provided for cooling the heat sealed end of the tubular film by a device which is independent of the sealing device. The heat sealed end of the tubular sleeve is positioned and directly engaged by the cooling members which serves to shorten the cooling time, yet provides an improved seal with an improved appearance.
