Abstract:
An orbital wrapping apparatus for wrapping a cargo in a stretch film is provided and generally includes a base frame, a circular ring assembly mounted on the base frame, a stretch film dispenser mounted on the circular ring assembly, and a cutting assembly mounted to the base frame and extending through an opening defined by the circular ring assembly. The stretch film dispenser includes a roll of stretch film dispensing the stretch film by rotation of the circular ring assembly, a subframe fixed to the circular ring assembly and the roll of stretch film is mounted on a loading assembly attached to the subframe, and a first feed roller and a second feed roller are mounted to a portion of the subframe that is movable between a first position adjacent to an axis extending through the first and second end caps and a second position spaced further apart from the axis. The cutting assembly is adapted to cut and hold the stretch film.
Abstract:
A printing apparatus includes a transfer mechanism that transfers a print medium, a printing device that prints on the print medium, a stationary blade that is provided on a downstream side in a transfer direction of the print medium further than the printing device to cut the print medium, a movable blade that is provided on a downstream side in a transfer direction of the print medium further than the printing device and that cut the print medium, and a step portion that is provided on a reverse face of the downstream blade which is located on downstream side in transferring of the print medium, the reverse face being reverse of a slide face of the downstream blade sliding on the upstream blade which is located on upstream side in transferring of the print medium, and that projects along a thickness direction of the downstream blade.
Abstract:
A method and apparatus for continuously producing pasted positive and negative electrode plates from pasted lead or lead alloy expanded, punched or cast metal mesh strip for use in lead-acid batteries without the use of paper barriers. The heating of cutting devices such as roll-mounted die-cutters to a predetermined temperature range of at least about 150° C., preferably about 160 to 300° C., and more preferably about 180 to 210° C., eliminates sticking of the paste on the pasted metal mesh strip to the cutting devices and obviates the need for the paper barriers.
Abstract:
The protective tape applied to the front surface of a semiconductor wafer to protect the wafer during backgrinding must be trimmed so that excess tape, known as tape bur, does not extend beyond the perimeter of the wafer. Tape bur may interfere with backgrinding by causing improper grinding, which may lead to wafer breakage. The tape cutter that trims the protective tape to eliminate tape bur is provided with a sensor which detects whether tape bur has been trimmed from the wafer. If tape bur has not been removed from the wafer, corrective action is taken to prevent the wafer from being backgrinded.
Abstract:
An autotaper for use in dispensing, cutting and locating tape. The autotaper is comprised of a base having a sliding mount attached to the base and disposed at an angle to the direction in which the tape is dispensed and a device for translating and positioning the sliding mount to a predetermined location on the base; and a feedhead attached to the sliding mount, having a rotatable shaft, a first feed roller mounted to the shaft in a manner that causes the first feed roller to rotate with the shaft when the shaft is rotated in a first direction and not to rotate with the shaft when the shaft is rotated in a second direction, a second feed roller rotatably attached to the feedhead that is in frictional contact with the first feed roller such that the second feed roller rotates in conjunction with the first feed roller, a device for cutting the tape, a linkage assembly attached to the shaft such that the linkage assembly rotates with the shaft when the shaft is rotated in a second direction to activate the cutting device and not to rotate or activate the cutting device when the shaft is rotated in a first direction, and a device for rotating the shaft for a predetermined amount in either the first or second directions.
Abstract:
The invention provides a method for applying labels to articles moved one by one past an application station. The labels are cut from a web which is fed through the machine, the web having adhesive applied to one side thereof which is pressure sensitive immediately before application to the articles. The machine includes cutting rollers which cuts through the adhesive side of the web in order to sever the labels therefrom, and the cutting edges of the cutting roller are kept clean by applying thereto liquid silicone or the like release composition. The liquid silicone is preferably applied by means of sleeves impregnated with the liquid silicone, such sleeves being rotatable on a spindle which is parallel to the axis of rotation of the cutting roller.The machine also has gearing coupling a device for feeding the web of materials to the cutting location. The cut labels are held by a vacuum drum before being applied to the articles and the gearing is also coupled to said vacuum drum.The machine is designed to operate continuously so that high speed application of the labels to the articles can be achieved.
Abstract:
A film dispenser and slitter is described which is comprised of an upstanding ladder-like support member which has forward and rearward ends. An elongated horizontally disposed support is mounted on the upper end of the support member and has opposite ends. First and second roll support members are mounted on the support for supporting a roll of film therebetween above the support. The roll support members are selectively slidably mounted on the support to permit the apparatus to accommodate rolls of various lengths to be supported therebetween. First and second bracket members are positioned at the opposite ends of the support and extend upwardly therefrom. A first film support bar is secured to the first and second bracket members and extends therebetween above the support. A film holding bar assembly is pivotally mounted on the first and second bracket members and includes a film holding bar which is pivotally movable from an inoperative position generally above the first film support bar to an operative position wherein the film holding bar is closely positioned adjacent the forward end of the support to yieldably maintain a sheet of film therebetween. At least one film slitter is selectively movably mounted on the support for slitting film as a sheet of film is pulled downwardly from the roll of film positioned thereabove. The support has a horizontally disposed film cutting edge provided thereon for facilitating the sheet of film to be cut to a predetermined length. The first film support bar has a vertically disposed forwardly presented surface whereby the upper end of the sheet of film, after the sheet of film has been cut to the desired length, may be moved upwardly from the film cutting edge and secured to the forwardly presented surface for facilitating the removal of any backing material from the sheet of film.
Abstract:
THE DISCLOSED INVENTION IS DIRECTED TO A NEW AND NOVEL ROLL MEANS FOR ADVANCING PRESURE-SENSITIVE TAPE IN AN APPLICATOR. DESIRABLY, THE APPLICATOR IS OF THE TYPE WHEREIN INDIVIDUAL SECTIONS OF TAPE MAY BE DISPENSED, SECURED AND SIMULTANEOUSLY PUNCHED WITH A HOLE THROUGH BOTH THE SECURED TAPE AND THE SHEET.
