An automatic machine for hot laminating a dry photoresist film (3, 4) supported on a peelable-off cover sheet onto a board (1) for printed circuit, includes at least a pair of hot laminating rolls, transfer means for feeding a preheated board to the inlet side of said pair of laminating rolls (11, 12), at least a supply roll of a rolled-up continuous ribbon of said supported dry photoresist film, vacuum means holding (5, 6) a free end portion of the supported dry photoresist film ribbon, means for pressing and tacking the leading edge of said vacuum held free end portion of the ribbon at a given position on a surface of a board moving towards the inlet side of said pair of laminating rolls, cutting means (17, 18) associated to said ribbon end holding and tacking means for cutting to measure, on account of the length of the fed board, the dry photoresist film ribbon carried along by the moving board (1) onto which the leading edge of the ribbon has been tacked by said tacking means, and means (13, 14) for heating said supported dry photoresist film at a certian temperature before laminating it through said pair or rolls. Said holding, tacking and cutting means translate together with the board (1), said holding, tacking and cutting means translate together with the board (1) and then return to their start position.
