Abstract
A blow box for suspended guidance and/or conveyance of strip material or sheets in which the blow means is blown with the effect of a blow jet issuing from a slot nozzle at an incline against the strips or sheets to be guided and/or conveyed. The blow box includes a barrier wall provided with blast openings which are arranged therein facing the strips or sheets so as to be close to one another in a row and have blowing directions which are substantially the same or which slightly diverge towards the ends of the blow box. Each blast opening is formed by a tongue positioned in the barrier wall, the tip of the tongue being sunk into the blow box, and an inclined guide surface which is arranged with its edges around the tongue and which is sunk into the blow box, together with the edges of the guide surface which overlap into the barrier wall.
