The embodiment includes: a roll accommodation unit that accommodates a roll of a continuous sheet of additional member; an unwinding unit that unwinds and draws the additional member from the roll accommodation unit to a trimming station; a trimming unit that is arranged in the trimming station and cuts and trims the additional member in accordance with the size of a book block to form a strip of additional member; a gripper that grips the strip of additional member while supporting the under face thereof, moves between a retracted position inside a housing and a forward position outside the housing, and moves between the forward position and a raised position above the forward position; and a handover unit that hands over the strip of additional member from the trimming station to the gripper located in the retracted position.

The first cutter that cuts, in the direction transverse to the unwinding direction, a continuous sheet of additional member unwound and drawn by a length in accordance with the thickness of the book block is arranged at the input port of the trimming station, the transport mechanism that transports the cut additional member from the first cutter out in the unwinding direction of the continuous sheet of additional member is arranged downstream of the first cutter, the second cutter that trims the cut additional member being transported on the transport path in the unwinding direction is arranged in the transport path of the transport mechanism, and the position of the blades of the second cutter may be adjusted in the direction transverse to the unwinding direction in accordance with the head-to-foot length of the book block.

A web material dispenser tear bar, a dispenser assembly comprising a tear bar and a method of forming the same. The tear bar includes a cutting edge that is defined by a plurality of teeth that extend along a longitudinal edge of a body of the tear bar. The teeth include a first group of teeth that have a triangular shape defined by linear edges of the respective teeth and a second group of teeth where at least one side of each tooth of the second group of teeth have a curved edge that extends in a radial direction toward an adjacent one of the plurality of teeth. The tear bar is preferably disposed in the housing of a dispenser and oriented to engage a web material to selectively perforate and/or sever a portion of the web material from the roll.

A feed assembly for dispensing rolled web material from a bulk roll of material and that includes a feed drum and a pair of pinch rollers that cooperate with the feed drum. The feed drum and pinch rollers are oriented and constructed to mitigate jamming and/or undesired displacement of the web material as it progresses through the feed assembly. Preferably, a drum guard is disposed between the pinch rollers and is constructed to further mitigate undesired translation of the web material relative to the feed assembly during dispense operations.

The present invention relates to an automatic package device, which may include a rack and a power control box provided on the rack. The cutter blade transportation device is provided on the rack along the X axis direction. Below the cutter blade transportation device and inside the rack, lower film feeding device is provided. At the rear side of the rack, the upper film feeding device is provided. At the front end of the cutter blade transportation device and on the rack are provided a blade feeding rail and cutter blade carrying device cooperating with each other. At the rear end of the cutter blade transportation device is provided a film sealing device which cooperates with the upper film feeding device and lower film feeding device. At the rear end of the film sealing device and on the rack is provided a dragging device fitting the blade strip. At the back side of the dragging device is provided a transverse cutting device fitting the blade strip. The present invention may achieve automatic feeding by the cutter blade carrying device. The dragging device may extend the upper and lower film material back and forth repeatedly. And the hot-pressing process may be accomplished by the film sealing device. The present invention may automatically seal the blades and the cutting device may separate the product one by one. At last the packaging process may be accomplished with high degree of automation and greatly improve production efficiency.

The present disclosure relates to the technical field of gummed tape dispensers, and more particularly relates to an electric water activated gummed paper tape dispenser. The dispenser includes a box body, wherein a paper feeding bin, a paper pushing mechanism, a dispensing mechanism, and a paper wetting mechanism are independently arranged according to functions in sequence in the box body, so that the overall structure is simpler, which is conducive to subsequent maintenance. In addition, one side of the box body is fixedly connected with an outer hood, a control system is arranged in the outer hood, and the control system is a PLC all-in-one machine. A paper pushing motor of the paper pushing mechanism and a dispensing motor of the dispensing mechanism are both full-digital subdivision stepper driven motors and are controlled by the control system, which is used as a core electronic control part of the device. During working, the control system controls operation of the paper pushing motor of the paper pushing mechanism so as to accurately control a pushing length of a gummed tape, and controls the operation of the dispensing motor of the dispensing mechanism so as to accurately control the dispensing amount of the gummed tape, thereby effectively ensuring the quality of the dispensed gummed tape and then improving the dispensing quality and efficiency.

A tape dispenser, including: a main body, including a base and a reel member, the reel member being connected to the base and movable between a plurality of positions relative to the base; an installation portion, connected to the main body, configured for installation of a tape; and a control portion, mounted to the base; wherein the control portion operates to allow movement of the reel member so that the reel member is switched to and restricted to be in one of the plurality of positions.

A perforation device includes a shaft, a perforation motor, at least a first perforation portion, at least a second perforation portion, at least a first cam for reciprocating a first perforation blade in the first perforation portion, at least a second cam for reciprocating a second perforation blade in the second perforation portion, a rotation speed detecting portion, a home position detecting portion, and a controller. in second perforation processing in which the shaft is rotated one turn to perform first perforation with the first perforation portion and second perforation with the second perforation portion in sequence, the controller senses, with the rotation speed detecting portion, the rotation speed of the shaft after the first perforation blade penetrates the sheet in the first perforation and, based on the rotation speed detecting, the controller determines the timing of starting braking control in the second perforation and performs braking control.

A sheet post-processing apparatus that performs post-processing on a sheet on which an image is formed includes: a punch hole forming portion; and a sheet bundle forming portion that has a conveyance portion, stops a first sheet on a conveyance path, and conveys a second sheet after the first sheet to a position overlapping the first sheet to form a sheet bundle. The sheet post-processing apparatus includes a shift portion to make a shift so that a relative position between the first sheet and the second sheet in a direction orthogonal to a conveyance direction becomes a relative position at which the second sheet does not overlap a punch hole of the first sheet to make the second sheet overlap the first sheet, and forms a sheet bundle in which sheets overlapped with each other are deviated in a width direction.
