Abstract: The present invention relates generally to pouches, and more particularly to a former to form pairs of dispenser pouches of the flexible three-sided sealed type. The former has a continuous foil channel and outer guide surfaces for a foil strip to be reshaped into a double tube, which enters the channel through a foil supply edge. A pair of form- and filling pipes are arranged in the channel, which has a back wall, two front walls having two form edges, and sidewalls that are adapted to the cross-section form of the filling pipes. The wedge-shaped form edges of the front walls delimit a slit in the lower part of the former. The back wall and the form edges of the front walls, proceeding from the foil supply edge and a section that converges in continuous direction between the front walls, are developed relative to one another and continually approaching until the end of the downwardly open slit.

Abstract: A three-sided pouch formed from a sealable foil comprises two parallel longitudinally extending tubular chambers. A longitudinal bendable sealing seam separates the chambers. Transversely extending sealing seams close the opposite ends of the tubular chambers. In order to enable such pouches to be easily opened, one of the transversely extending seams has a widened portion straddling the longitudinally extending sealing seam and extends to both tubular chambers. A tearing aid for facilitating the tearing open of the two tubular chambers is arranged in the widened portion.

Abstract: The invention relates to tubular bag-type packings and, in particular, it relates to so-called three-sided pouches formed from a sealable foil and comprising two longitudinally extending tubular chambers. The chambers extend parallel to each other and have opposite ends. A longitudinally sealing seam separats the chambers, and the sealing seam is bendable. Transversely extending sealing seams close the opposite ends of the tubular chambers. In order to enable such packings to be easily opened, one of the transversely extending seams has a widened portion straddling the longitudinally extending sealing seam and extends to both tubular chambers. A device, i.e. a tearing aid for facilitating the tearing open of the two tubular chambers is arranged in the widened portion.

Abstract: The invention is concerned with tubular bag-type packings in the form of so-called stickpacs formed of a sealable foil strip of at least one layer which is molded to form a tube provided with a longitudinal sealing joint extending between the side edges of the packing. The tube is sealed by upper and lower transverse sealing joints. In order to enable such stickpacs to be easily and faultlessly opened, in one instance, also in the area of the longitudinal sealing joint, tearing aids are provided, and in another instance, the tube, via a transverse sealing joint, is provided with an extension, with the transverse sealing joint being arranged to extend at an inclination relative to the longitudinal axis of the packing.

Abstract: A robotic manipulator having a gripping tool assembly for separating a thin sheet of metal from a stack of metal sheets. The assembly comprises a frame mounted to a lift arm. A separating device is pivotally mounted to the frame for grasping and lifting a corner of the top metal sheet to create an initial separation of the sheet from the stack. A plurality of stationary suction lifters are secured to the frame for grasping and lifting the remaining portions of the top sheet. The gripping tool assembly is characterized by first and second air hoses or nozzles mounted to the frame with the first air nozzle positioned above the second air nozzle whereby the first air nozzle provides pressurized air toward the corner of the sheet to assist in the initial separation of the sheet and the second air nozzle provides pressurized air below the sheet after the initial separation of the sheet from the stack.

Abstract: A tool for cutting and shaping a lower edge of a profiled unfinished concrete roofing tile manufactured using the extrusion method, having a tool holder, a cutting insert provided with a cutting edge, and a template. To create a tool which has a significantly increased useful life for cutting and shaping an unfinished concrete roofing tile, the invention teaches that the tool holder and the template are realized in one piece in the form of a support body with a recess for the adhesive and positive connection of the cutting insert, that the cutting insert is made of tungsten carbide and is fastened in the recess by means of adhesive, and that the cutting insert is in contact by means of its upper edge with at least one projection of the support body.
