Abstract: The present invention relates to a method and apparatus for producing communication articles such as postcards, envelopes or the like in each of which display surfaces for information or the like are separably bonded with a synthetic resin therebetween by heating for concealing information such as correspondence or a printed display medium and then mailing it. It is an object of the invention to enable easy and smooth separating of a film-containing sheet and accurate insertion of a film in a sheet.

Abstract: This invention relates to an automatic film feed register device for feeding film to a bag manufacturing device, in which setting of the film intermittent feeding pitch can be done by a keyboard of a microcomputer by an unskilled worker not withstanding whether the machine is operating or stopped. The machine has intermittent feed rollers for a film, a crank connected to the feed rollers through an electromagnetic brake and an electromagnetic clutch, a device shaft for said crank, and an adjusting device for adjusting the eccentric distance of the crank, characterized by an adding mechanism provided between the drive shaft and the adjusting device for adjusting the eccentric distance of the crank. The motion of a drive shaft is controlled by a microcomputer input into the adding mechanism.

Abstract: Phase control device comprising a driven wheel and a driving wheel. The driven wheel engages an endless loop, whose going part toward the driving wheel and returning part from the driving wheel engage a pair of idling wheels and one or plural pairs of movable wheels. The movable wheels are finely adjusted toward a cross direction to the endless loop so that either the going part and the returning part is pulled, while the other is slackened. As a result, the phase of the driven wheel is changed so that timing of the driven wheel against the driving wheel can be regulated. The phase control device provides timing of the operation of a pair of machines such as coveyors which link mutually.

Abstract: A system for controlling and synchronizing the operation of a conveyor system and an article supply system. An encoder monitors the operation of a standard reference or dispensing device along with a rate detecting device. This information is fed into a computer employing a microprocessor. The microprocessor provides an output to a drive system for a conveyor or the like to be synchronized with a supplying or dispensing system.

Abstract: Film running one direction is folded along a longitudinal folding line by a folding plate and folding blade. The folding plate has a front edge and an inclined edge extending in the lateral direction against the film feeding direction, the folding blade extending in an oblique direction against the film feeding direction from the apex point of said edges of the folding plate for folding the outer part of a film against the reverse side of the film. The edges of the folding plate receives the tensile force of the film along the whole width so as to avoid any concentration of tensile force.

Abstract: In a container filling apparatus having a plurality of revolving charging cylinders and respective pistons by which a fluid material supplied into the cylinders with their pistons at the limit end of their intake strokes is subsequently pushed out of the cylinders to fill respective containers, an adjusting screw is provided to set by its one end the limit of the intake stroke of the piston rod of each piston and has a sprocket-like wheel fixed to its other end and actuated in incremental rotation by the piston rods of stationary air cylinders fixed to the apparatus frame when the wheel, revolving with its cylinder, is engaged by the piston rods. The activation of the air cylinders is controlled by electrical control means by which the limit of the intake stroke of any piston and, therefore, the filling quantity of the corresponding cylinder can be adjusted without danger and without stopping the operation of the apparatus.

Abstract: In a container filling apparatus having a plurality of revolving charging cylinders and respective pistons by which a fluid filling material supplied into the cylinders with their pistons at the limit end of their intake strokes is subsequently pushed out of the cylinders and through nozzles to fill respective containers at a filling position, the containers being preparatorily positioned on respective revolving platforms, the piston rod of each of the charging cylinders can be locked at the start of its intake stroke by a respective locking mechanism when the mechanism, as it revolves with the cylinder, contacts and is actuated by a stationary actuating device operated in accordance with a detection signal generated by a monitoring device. When this monitoring device detects the absence of an empty container from its preparatory position on any platform, it generates the detection signal to lock the corresponding piston rod thereby to prevent containerless discharging of the filling material.
