Abstract:
A continuous web of closed, preformed end-to-end bags for enclosing bales of material are made by forming an elongate sheet into a helix tube, flattening the tube into first and second elongate bag walls and securing the bag walls at closure seams located along the flattened helix tube. The helix tube is formed by nesting the elongate sheet side edges into U-shapes and sewing. The bag walls are secured to one another by nesting them into U-shapes and sewing. Bales are enveloped by severing the web and thereby providing a bag with an open end, separating the bag walls, inserting a bale therein, closing the bag and severing from the remaining web. Each bag is located along the web with a pair of sensors which provide a locating signal responsive to the bag closure seams.
Abstract:
This disclosure relates to foiiuing food packages with a lap seal. A continuous, peelable hermetic seal is formed by activating a conductive element to emit an electrical impulse while contacting the overlap region of a pouch. The overlap is sealed by the heat generated from the activation of the conductive element, for example a wire. The conductive element is placed longitudinally along the overlap area of the pouch, which results in a sealed line. A second parallel sealed line may also be made to add redundancy, thereby better sealing the pouch. The disclosed method results in a package with an unsealed flap between first seal line and the film edge that allows for easy opening of the pouch.
Abstract:
Device for checking objects composed of a plurality of parts, layers or the like with the aid of a checking set (23) past which the object, in particular a cigarette group (12), a material web or the like is moved, reflected light from the object being picked up by an optoelectronic checking member, specifically by a CCD linear array chip (10) which is arranged transverse to the direction of movement and/or transverse to the longitudinal extent of the object. A profile of the object is taken by the CCD linear array chip (10) by means of regions of different light intensity, and processed in an evaluation unit.
Abstract:
A bagging assembly for bagging bales of fibrous material is disclosed. The bagging assembly incorporates a chute defining a channel for receiving a bale, which is pushed there between by a stuffing assembly. Aspects of the bagging assembly include raising a bale using a bale elevator to a higher elevation position so that the bale could be stuffed by the stuffing assembly and using a bag retrieving mechanism for retrieving a bag from a bag location for use in bagging the bale.
Abstract:
An apparatus for closing and sealing a preformed polypropylene bag after a bale has been inserted therein as the bale and bag traverse along a longitudinal line of travel. Left and right rotatable side flaps fold the left and right bag closure flaps onto the bale. A bottom rotatable fold plate partially folds the bag bottom closure flap and a top fold bar is extended and folds the top bag closure flap onto the bale. The bottom fold plate then folds the bag bottom closure flap onto the bale. The top and bottom bag closure flaps are sandwiched between the rotatable side flaps and the bottom fold plate and over a slack bar therebetween forming a slack portion. A heating assembly directs heat to the slack portion melting the polypropylene and a press plate is extended to the slack melted portion thereby fusing the bag closure flaps together.
