Abstract: A wrapping machine of the present invention comprises a wrapping portion for wrapping a material, a film feeder for feeding a wrapping material (film) to the wrapping portion from a film roller, a material feeder for feeding the material to the wrapping portion, a film folding device for wrapping the material with the film at the wrapping portion, and a material transfer device for transferring the wrapped material. When a material is placed on a conveyer of the material feeder, the material abuts on a stopper to temporarily stop, and then is transferred to a lift of the material feeder. The width and length of the material are detected during the transfer. The lift then moves upward to supply the material to the wrapping portion. The film drawn from the film roller by the film feeder is supplied to the wrapping portion where the material abuts on the film from below so that the upper portion of the material is covered with the film. The film is then folded under the material by the film folding device.

Abstract: A wrapping machine used to wrap with a prescribed wrapper a commodity having the shape of a hexahedron having a length, a width, and a height, as well as a top surface, a bottom surface, a front surface, a rear surface, a right side surface, and a left side surface; in this wrapping machine, the commodity being wrapped in a wrapping region, this wrapping region having a central position along the length of the commodity, and a reference wrapping position along the width of the commodity; the wrapping machine further comprising: a wrapping supply device that holds at least two wrappers of different sizes, and selectively supplies either of the wrappers to the wrapping region; a sensing device, provided in the wrapper supply device, that detects the sizes of the wrappers; a control device electrically connected to the sensing device, as well as operationally connected to the wrapper supply device; this control device has a display device, and it determines whether the sizes of the wrappers are within the usable

Abstract: A bag covering apparatus that puts a cover, which has been folded in two at the folding portion, on the opening of a bag. The same bag covering apparatus includes a folding piece which can operate to fold the cover in two at the folding portion and a cover retaining piece provided near the folding piece, having at least two holding portions capable of holding the folding portion of the cover. The folding portion of the cover is inserted into the holding portion of the cover retaining piece by the action of the folding piece, the cover retaining piece being movable such that when one of the holding pieces of the cover retaining piece faces the opening of the bag, the other holding piece of the cover retaining piece faces the folding piece.

Abstract: A bagging machine comprising a bag supply device, a bag-opening device, a bag-sealing device mounted on one side of the bag-opening device, and a bag-moving device. The bag supply device includes a mounting member and a first bag-attracting portion mounted to the mounting member that reciprocates between a bag supply position and a bag opening position. The bag-opening device has a second bag-attracting portion which faces the first bag-attracting portion when the mounting member of the bag supply device is in the bag opening position. The second bag-opening portion can move toward and away from the first bag-attracting portion. The bag-moving device has a pair of openable holding members. The holding members reciprocate between the bag-opening device and the bag-sealing device, and close the opening of a bag by holding the opening between themselves.

Abstract: A wrapping machine comprises: front and rear folding members movable relative to each other in the longitudinal direction of the machine; a pair of lateral folding members respectively positioned at both lateral sides of the rear folding member, the lateral folding members being opened and closed with respect to each other in response to the longitudinal movement of the rear folding member; a folding area defined between the front and rear folding members and the pair of lateral folding members, in which folding area the edge portions of a piece of wrapping film are gathered together tightly underneath an object to be wrapped; and a pair of mounting members positioned above the pair of lateral folding members, respectively, and entering the space underneath the object so as to mount the same thereon before all of the folding members enter the space underneath the object so as to fold the piece of wrapping film.

Abstract: In a method and device for barrel-binding and packaging articles, a first end of packaging material is pinched between a fixed seal member and a first pinching member movable with respect to the fixed seal member. The first end and a coupling end of the packaging material is pinched between the fixed seal member and a movable seal member confronting the fixed seal member with the articles bound by the packaging material. The coupling end is then pinched between the first pinching member and a second pinching member and a pushing-in member is inserted between the fixed seal member and the first pinching member in response to separation of the first pinching member for pinching the first and coupling ends. The first and coupling ends of the packaging material are then joined between the fixed and movable seal members while they are pinched between the seal members and thereafter the coupling end is cut by a cutting blade at the inserted end of the pushing-in member.

Abstract: Disclosed is a method of packing an article which comprises the steps of: stretching and gripping a packing film; sending an article onto a reception block having a turning belt for mounting the article thereon, under the packing film; moving up the article together with the reception block so as to urge the article against the packing film; moving thereafter the reception block and a tuck block situated in an article send-in side of the reception block, to an article send-out side of the same, thereby shifting the article from the reception block to the tuck block, the packing film being put in a state where one end portion of the packing film is extended down through a gap between the reception block and the tuck block and gripped thereat, in shifting the article; moving a mounting portion of the belt of the reception block in a direction opposite to the direction of movement of the reception block and the tuck block, in shifting the article; and tucking-in the one end portion of the packing film under the

Abstract: Disclosed herein is a packing apparatus which comprises a container opening at its upper end and at least one film suction chamber positioned under the container and is connected to an appropriate absorbing device. The container defines a packing chamber for holding a part of a packing film in a baggy shape and receiving products to be packed therein. The suction chamber defines a chamber communicating with the absorbing device. The chamber further communicates with the packing chamber through a plurality of vent holes for creating a partial vocuum under the packing film.
