Apparatus for feeding strips coated with a fusion adhesive on one of their surfaces to a sheet-stack binding apparatus, in particular, for the binding of loose sheets to form brochures or books, such apparatus enabling, in parallel with a binding operation, a strip cut to the required length to be made available for a subsequent binding operation. The apparatus (14) arranged in the strip path downstream of a cutting unit (12) includes a transport carriage (15) which is stationary with respect to the strip path (13) and movable vertically to the strip path and on which a horizontally movable element (16) as well as a plurality of stationary mechanical elements (11, 17) are arranged for holding the strip free from torsion. Driving means (19), control means, as well as a tilting device (18) are provided for transferring transport carriage (15) to a binding apparatus (21) which is arranged vertically to the strip path (13) and holds the sheet stack (22) such that the strip rests on the spine of the sheet stack in a centrally aligned position and is fixed by holding elements (23) of the binding apparatus (21).

Method and apparatus for feeding strips having a fusion adhesive coating on one of their surfaces to an advancing transport unit, in particular a sheet-stack binding apparatus where loose sheets are bound to form brochures or books. The method is carried out in that a thickness range of a sheet stack to be bound is associated with a specific width of a strip coated with a fusion adhesive, in that the association is effected in that the thickness of the sheet stack to be bound is determined or in that a selectable predetermined value is provided and in that the sheet-stack thickness value preselected or determined is used to control a drive mechanism (5, 6) which transfers the strip associated with the thickness range of the sheet stack to be bound from separate standby positions (7') of a number of strips (1c, 1d) of different widths to a handling position (12').

The invention relates to a flash device, preferably for transferring a dye matrix which by means of a high-energy light flash is transferred from a radiation-absorbing carrier film by interleaving a mask onto a receiver element. This requires substantially perpendicular irradiation of the transfer plane with a high-energy radiation and a high uniformity of irradiance distribution of the light flash. To achieve this, one or two linearly extending plasma discharge tubes are provided which to concentrate radiation are enclosed by two separate aspheric-cylindrical reflectors, the concentrated radiation being directed through a lamellar louver element arranged downstream of the reflector and impinging on the predetermined transfer plane in a substantially parallel and perpendicular manner.
