Abstract: The device pertains to providing side shift force control using load cell force feedback in the web slitting industry. Further included is a removable means of providing the load cell force feedback without integrating the load cell with the side shift mechanism. This provides for easy maintenance of the blade cartridge and specifically the cutting blade.

Abstract: A tin-tie bending device for bending the ends of a tin-tie about the edges of a bag wherein the tin-tie is secured to across the width of the bag and the ends of the tin-tie extend beyond the edges of the bag prior to bending. The device includes means for moving the bag along a travel path past a detecting means and a bending means of the device. The detecting means detects the bag as it travels past the detecting means. The bending means bends the end of the tin-tie about the edge of the bag and is actuated upon the detecting means sensing the passing of the bag along the bag travel path.

Abstract: In a packaging machine of the type in which a "tin-tie" strip is affixed to a bag to allow repeated reclosures of the bag, a machine for cutting a continuous strip of tin-tie material into predetermined lengths and feeding the cut lengths into a bonding station where they are adhesively bonded to the bag proximate its top opening. The machine comprises a frame supporting a pair of electromagnetic clutches, one for selectively coupling a continuously driven shaft to an output shaft to which a tin-tie strip feedwheel is attached and the other for selectively coupling a continuously driven shaft to an output shaft to which a rotary cutting head is secured. Passage of a bag past a sensor triggers the two clutches which function to withdraw a predetermined length of tin-tie material from a supply reel and to sever the strip while feeding the cut length to the bonding station at the same speed as the bag is moving.

Abstract: A case feeding apparatus moves open cases onto a lift table where each case is moved upwardly onto the funnel portion of a shifting grid structure so that a slug of articles can be deposited therein. Line pressure advances the cases toward a retractable stop and side belts move the cases individually into an intermittently operated pair of case conveyors capable of handling cases of different size. Arrival of a case at the lift table triggers both the raising and lowering of the lift table and an indexing device controls the case conveyor cycle. The cases have their side flaps folded down by side guides to maintain the case in laterally centered positioned on the lift table and each case conveyor has either pusher lugs or leading lugs to control case position longitudinally.

Abstract: An improved machine for automatically applying transfers such as tax stamps to multiple packages contained in a carton is disclosed. The machine comprises a conveyor for advancing a carton through an opening station, where it is opened to expose the packages therein, through a stamping station, where tax stamps in the form of heat or water transfers or ink printing are applied to each of the packages by a movable platen, and through a closing station where the carton is closed and resealed. The machine is adjustable to accommodate a variety of carton and package sizes and to apply the transfers to a selected part of each package in the carton accurately, while using stock transfer sheets on which the transfers are mounted with a predetermined spacing that does not necessarily correspond to the spacing of packages within the carton.

Abstract: A packaging machine in which a belt-shaped packaging sheet fed continuously is cut to a predetermined length while being guided and conveyed in a direction intersecting the conveyance direction of articles to be packaged. Position detectors detect the arrival of the top end of said packaging sheet, detect the arrival of each article at a position before the position where said article crosses said packaging sheet and the arrival of the top end of the packaging sheet returned from the feeding limit position by being moved as said article abuts against said packaging sheet and is further conveyed, at a predetermined reverse return position. The detectors are used to generate the necessary control signals for feeding and cutting the packaging sheet.

Abstract: A machine for automatically applying transfers such as tax stamps to multiple packages contained in a carton is disclosed. The transfer applying machine comprises a conveyor for intermittently and sequentially advancing cartons through an opening station, where the carton is opened to expose the packages therein, through a stamping station, where tax stamps in the form of heat or water transfers or ink printing are applied to each of the packages, and through a closing station where the carton is closed and resealed. The machine is adjustable to accommodate a variety of carton and package sizes and to apply the transfers to each package in the carton accurately while using stock rolls of transfers on which the transfers are mounted with a predetermined spacing that does not necessarily correspond to the spacing of packages within the carton.

Abstract: An apparatus and method is disclosed for inserting sheet material into a quantity of envelopes. The envelopes are conveyed in seriatim along a conveyor to an indexing drum. The envelopes are shingled and respectively overlap each other as they approach the drum. The indexing drum simultaneously receives one envelope from the conveyor, while discharging another envelope to an inserting deck. Each discharged envelope is restrained, and then sheet material is inserted therein. A sensor disposed upon the inserting deck, respectively senses each discharged envelope and provides a signal to actuate the inserting mechanism, and deactuate the indexing drive. When an inserted envelope leaves the deck, the sensor then actuates the indexing drive to cause the drum to discharge another envelope.
