Abstract: A method and apparatus for separating flexible flat objects from the top of a stack. The objects are lifted upward from the stack one at a time and separated therefrom by progressive adhesive action starting from the trailing end of the object in a transport direction. Once lifted by the adhesion device, the objects are transported in the transport direction by the transport device. The adhesion device may be magnetic for magnetizable articles or may be a suction device. Various techniques for moving suction and/or adhesion progressively along the object to be lifted in the transport direction are disclosed, including progressive application of suction, suction chamber arrangements for accomplishing that and the use of blown air to create a vacuum condition for lifting the sheets. The transport device might comprise a belt for moving the lifted objects. The transport of one object may be occurring while the next object is being lifted.

Abstract: A device in an axially extending tension channel on the circumferential surface of a cylinder for fastening a flexible plate on the cylinder periphery. The leading edge of the plate is held by a leading edge fastening device in the channel, and the trailing edge is held by a trailing edge fastening device in the channel. The leading edge fastening device is a start hook-in bar which the leading edge of the plate engages. The trailing edge fastening device is formed by an end hook-in bar which is engaged by the trailing edge of the plate. The end hook-in bar projects tangentially from a tensioning shaft which is rotatable to set the tension of the plate without means to apply a clamping load. Various devices for fastening and adjusting the leading and trailing edges of the plate are disclosed.

Abstract: A method for the positionally accurate feeding of sheet-like objects to a treatment process, the objects being conveyed in succession in a lying position and being aligned during the conveyance. Rotational movement of the conveyed object is carried out to correct a skew position of the front edge of the object, a lateral movement of the object is carried out transversely, in particular at right angles, to the conveying direction for lateral alignment purposes, and an accelerated or decelerated longitudinal movement in the conveying direction is carried out for longitudinal alignment of the object, all the alignment movements being carried out on the surface of an object and without any mechanical alignment action on one or more peripheral edges of the object.

Abstract: A method and a device for drying workpieces that have been provided with a fresh surface coating and are conveyed through a drying zone in a housing wherein hot air is applied to the workpieces to dry them. At least a fraction of the walls and/or built in component in the region of the housing to which the workpieces are conveyed have hot air applied to them for preventing formation of condensate. A hot air barrier may be provided at the inlet or the outlet of the drying zone. A material for bonding and storing liquid may be provided on at least a fraction of the walls and/or built in components.
