Abstract:
A method for regulation of temperature of heated air in an apparatus for pasting of plastic film,comprising the steps ofarranging a rack with a table (1) over which workpieces (2) are conveyed continuously by arranging a conveyor device therewith;disposing a conveyor roller pair (4,5) in a gap (3) of the table top (1) and supported in the rack and forming a roller gap essentially flush with the table surface and having a lower roller (4) which is a counter-pressure roller and an upper roller which is a suction cylinder 5;arranging a conveyor cylinder (7) to interact with the suction cylinder (5) which successively transfers sections (8) of the plastic film to the suction cylinder (5);directing a broad-slit nozzle (30) to the roller gap to blow heated air into the roller gap in a controlled manner,determining temperature directly after pasting of a pasted region of the workpiece at which a good pasting is performed as a nominal value; andregulating the temperature of heated air to this nominal value.
