  • Patent number: 6619647
    Abstract: In a device for loading further-processing machines with printed products, in particular a feeder rack (5) in gather-stitcher machines or gathering machines (6) for folded sheets (1), sheets, booklets or the like, which has a first conveyor arrangement (15) extending in planar manner for the purpose of feeding printed products (1) standing on their edges in the form of a horizontal stack (2), a second, initially upwardly sloping conveyor arrangement (16) for drawing the printed products (1) off the stack (2) in an overlapping formation and for transferring the overlapping stream (3) to the feeder rack (5), and infinitely variable drives (20, 24) associated with the two conveyor arrangements (15, 16), a control means (23) is provided which controls the two drives (20, 24) at a speed ratio to one another which is dependent on the thickness (D) of the printed products (1) to be processed.

    Abstract: In a device for loading a feeder rack (5) in further-processing machines such as gather-stitcher machines or gathering machines (6) for folded sheets (1), sheets, booklets or similar printed products, which has a first conveyor arrangement (15) extending in planar manner for the purpose of feeding printed products (1) standing on their edges in the form of a horizontal stack (2), a second, initially upwardly sloping conveyor arrangement (16) for drawing the printed products (1) off the stack (2) in an overlapping formation and for transferring the overlapping stream (3) to the feeder rack (5), infinitely variable drives (20, 24) associated with the two conveyor arrangements (15, 16), and a light barrier (31) arranged in the feeder rack (5), a control means (23) is provided by means of which the drives (20, 24) can be controlled in dependence on the degree of coverage (BG) of the light barrier (31), as a result of which the fill level of the feeder rack (5) remains at an at least substantially constant height

  • Patent number: 6035563
    Abstract: An electric iron has a soleplate with a front tip and at least one passage for a liquid stored in a liquid tank system for wetting an article to be ironed. The passage is arranged in the area of the front tip symmetrically to a central line which starting from the front tip divides the soleplate in the middle. The liquid exits the passage in the form of liquid droplets generated by a piezoelectrically driven sprayer arranged above the soleplate. The electric iron is characterized in that the sprayer (12, 13, 14, 29) has at least one piezoelectrically driven thin membrane plate (12) with a plurality of spraying holes (24) associated with the respective passage (11) of the soleplate (6) and having a mean clear width from 30 to 100 .mu.m. The number of spraying holes (24) is selected to ensure that the amount of liquid dispensed through the soleplate (6) does not exceed about 8 g/minute. The passages (11) are maximum 10 mm wide, whatever their length.
