Abstract:
A welding robot having an elongated arm pivotally mounted on an upright turret which is movable about the upright axis thereof. As a result, the arm is swingable about the aforesaid upright axis. A fine movement control device or commuter is mounted on an end of the air remote from the aforesaid pivotal attachment thereof to the upright turret. The fine movement control device has a welding gun mounted thereon with structure being provided in the control device for permitting the welding gun to move through a very fine pattern of movement independent of the movement of the arm. A preprogram is provided for moving the arm in a predesignated direction to coincide with the path of a welding seam. Variations of the welding seam from the preprogram can be controlled by the structure in the fine movement control device so that the welding torch will follow the actual welding seam even if it varies from the preprogrammed path thereof.
Abstract:
An apparatus for processing and conveying indexed stacks of sheets produced from wide stock, comprising: a cutting station for successively severing the stock lengthwise to produce parallel rows of side-by-side layers; a lengthwise conveyor for conveying the parallel rows of layers in a conveying direction; a spacing station disposed downstream of the cutting station for spacing the layers apart from one another in the direction transverse to the conveying direction; an index punching station disposed downstream of the spacing station and having a row of punches for removing parts of the lengthwise edges of at least some of the layers, at least some of the layers in each row being different from adjacent layers in the row; and, a transverse conveyor, adapted for incremental stepped conveying, disposed downstream of the index punching station, for receiving the spaced, punched layers and for producing stacks of indexed layers as the conveyor steps from one end of the row to the other. The apparatus may further comprise: a binding punching station disposed upstream of the index punching station; a printing station for printing an index inscription on a top sheet of the layers of sheets, disposed upstream of the index punching station; and, a laying-on station for an intermediate sheet, disposed upstream of the printing station.
Abstract:
An apparatus (24) for the simultaneous production of all the sheet layers, including pocket dividers, for blocks, as well as for the complete production of said blocks has a manufacturing or production means (25) for the pocket dividers folded along a fold line and glued along a line at angles thereto, in which the pocket dividers are simultaneously cohesively produced in multi-unit size form over the working width in the same way as the remaining sheet layers of the block, then the remaining multi-unit size partial layers of the block are supplied and finally are cut commonly into the individual units. This leads to a fully automatic production of blocks comprising pocket dividers without any intermediate storage of the pocket dividers and as each of the pocket dividers can be produced with only one single back layer, a considerable material saving is achieved.
