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.
Abstract:
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 clean air duct device comprises a duct (11) having a positive-pressure air channel (21), and a filter (12) provided between the inlet (24) and the outlet (31) of the duct. The filter (12) comprises a filter medium (41), and a frame (43) surrounding the medium (41) and having an upstream mount flange (45) along an edge portion thereof defining an upstream opening (44) and a downstream mount flnage (47) along an edge portion thereof defining a downstream opening (46). The duct (11) comprises an upstream duct member (22) and a downstream duct member (23). The upstream duct member (22) is provided at an outlet end thereof with an upstream communication opening (26) shaped in conformity with the shape of the frame upstream opening (44), and the downstream duct member (23) is provided at an inlet portion thereof with a downstream communication opening (33) shaped in conformity with the shape of the frame downstream opening (46). The upstream communication opening (26) has an upstream joint flange (28) along its edge portion, and the downstream communication opening (33) has a downstream joint flange (35) along its edge portion. The upstream mount flange (45) and the upstream joint flange (28) are connected together with an upstream packing (51) interposed therebetween, and the downstream mount flange (47) and the downstream joint flange (35) are connected together with a downstream packing (52) interposed therebetween.
Abstract:
A cam device includes an armlike cam follower for moving a lift unit upward and downward, and a plate cam having a cam contour face in contact with the cam follower. The cam is formed in a side surface thereof with a recessed portion having an inwardly facing periphery which provides a guide face extending along the cam contour face. A movable roller is in bearing contact with the guide face. The cam follower and the movable roller are biased toward each other by and elastic member.
Abstract:
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.
Abstract:
A device for reducing torque variations for use in a drive apparatus which has a drive shaft for causing a lift unit to perform one cycle of up-and-down movement for each of at least two lift units to perform one cycle of up-and-down movement at a specified interval by one turn of rotation of the drive shaft. The device comprises elastic means and transmission means for transmitting an elastic force of the elastic means to the drive shaft as a rotational torque.
Abstract:
A package container tube processing apparatus by which a vertical tube filled with contents is divided into lengths each corresponding to one container to form intermediate containers. The apparatus comprises a vertical rod movable upward and downward and reversibly rotatable, a movable frame attached to the vertical rod and movable therewith upward and downward while permitting the reversible rotation of the vertical rod, a pair of pressure arms supported at their lower portions by the movable frame so as to be pivotally movable about a pair of horizontal axes parallel to each other, a pair of seal bars fixed to the upper portions of the pressure arms respectively and opposed to each other, and conversion means for converting the forward-reverse rotation of the vertical rod to a pivotal motion of the two pressure arms to move the two seal bars toward or away from each other.
Abstract:
