A high-frequency heat-sealing apparatus is provided which is capable of achieving a satisfactory seal in which a sealed zone is narrower in its width than at its central portion and in which contaminants such as liquid beverages are not present between thermoplastic material layers over the longitudinal direction of the sealed zone. The apparatus transversely heat-seals a tubular packing material made of a laminate including a synthetic resin layer and a conductive material layer in the presence of a fluid. A ridge shaped to contain an arcuate partial curve in its transverse contour is formed on the action face of a high-frequency coil flush with the flat action face of one of the pressing members for pressing the central portion of a sealed zone having two rounded and narrowed right and left sides. A flash portion for a molten thermoplastic resin is formed adjacent to the outer side of the high-frequency on the cutting side of the coil.

A heat-sealing device for liquid-filled tubes has a pair of openable pressing members 23, 24. One of the pressing members, 23, is provided in a pressing face 31 thereof with upper and lower two pressing pads 34, 35 extending in parallel to each other for pressing the tube T along and at respective opposite sides of each of the portions to be cut. The other pressing member 24 is provided in a pressing face 36 thereof with a U-shaped high-frequency coil 38 having upper and lower two straight portions 42, 43 extending in parallel to each other for heating the tube T along and at the respective sides of each portion to be cut. The pressing face 36 of the other pressing member 24 has upper and lower sealer portions 44, 45 each divided into a primary sealing portion 51, secondary sealing portion 52 and tertiary sealing portion 53. When the pressing members 23, 24 are closed, the primary sealing portions 51, 51 are parallel to the forward end faces of the pressing pads 34, 35 respectively, and the secondary sealing portions 52, 52 are so inclined as to gradually recede from the forward end faces of the respective pads 34, 35 as the sealing portions 52 extend outward.

An apparatus for continuously unwinding a plurality of rolled-up tapes made of fusible material wherein the tapes are successively unwound, one at a time, from at least two rewinders for supporting the tape thereon, with the tail end of the preceding tape joined to the leading end of the following tape. The apparatus comprises a guide roller assembly for transporting the preceding tape via a joining station, a tape end sensor for detecting the tail end of the preceding tape, and a joining device for holding the following tape at its leading end as folded over and opposed to the preceding tape, thermally bonding the tail end of the preceding tape to the folded-over leading end of the following tape in response to a detection signal from the tape end sensor, and cutting off a portion of the resulting joint with only a required length thereof left uncut.

A heat sealing device for a tubular packaging material which is made of a heat-sealable paper-base laminate having an aluminum foil layer and which is to be cut transversely thereof into lengths comprises a U-shaped high-frequency coil provided in a pressing surface of one of a pair of press members and having two straight portions extending in parallel to each other for heating the packaging material at opposite sides of each cutting portion therealong. Two strip-like magnetic members are arranged on the outer side of the respective straight portions and extend approximately over the entire length of the straight portions. Each of the two straight portions has a ridge extending longitudinally of the straight portion at each of two portions of the entire length thereof for individually applying an increased pressure to opposite side edge portions of the material. The ridge has a circular-arc contour in cross section.

A process for producing bean curd comprising the steps of cooling soybean milk and bittern individually to below the coagulating temperature of the milk, mixing the cooled milk and bittern together and filling the mixture into buckets, coagulating the mixture in the buckets by heating, and withdrawing the coagulated milk from the buckets and detwatering the coagulated milk to obtain formed bean curd. An apparatus for practicing the process comprises a mold box and a pressing closure each having in a required portion a multiplicity of holes not passing the coagulated milk therethrough but permitting the water contained in the coagulated milk to pass therethrough.

Apparatus for processing bean curd

A bean curd producing machine comprising soybean milk coagulating means, means for dewatering and shaping coagulated soybean milk and means for delivering bean curd shaped by dewatering. The coagulating means comprises a bucket conveyor disposed within a heating chamber and having coagulating buckets arranged in parallel rows, and a distributing trough disposed above the paths of travel of the buckets in all the rows thereacross and formed in its bottom wall with filling openings positioned immediately above the respective rows of buckets. The dewatering-shaping means comprises a bucket conveyor having press buckets arranged in parallel rows and each formed in a required portion with many dewatering apertures, a press bar disposed above the paths of travel of the press buckets in all the rows thereacross, and lids suspended from the press bar each by a spring, equal in number to the number of the press bucket rows and each provided for one press bucket. The delivering means comprises a lift disposed below the lower path of movement of the press bucket conveyor and having chucks for holding the press bar, and means for moving the lift upward and downward at a variable speed so that bean curd can be delivered as placed on the lids from the press buckets without collapsing.

An apparatus for processing baglike container blanks by fitting the blank around a pair of forming plates arranged at a distance from each other in parallel, folding a pair of triangular ears flat while projecting the ears sidewise from the portion of the blank to be made into the bottom of a finished rectangular parallelepipidal container, and press-bonding the projected ears to outer surface portions of the trunk of the container at the lateral sides thereof after folding the ears over the outer surface portions. The apparatus includes a device for press-bonding the triangular ears, which comprises a pair of press members and a support member positionable therebetween. Each lateral side trunk portion and each ear folded thereover are clamped between the support member and the press member respectively from inside and outside the blank.
