ABSTRACT:
An apparatus for regulating the length of divisional spacings of a metal band comprises at least two workpiece conveying roller pairs spaced from one another in the direction of the workpiece length and arranged for holding and advancing the workpieces in the direction of workpiece length; a scanning device for determining the actual length of the workpieces during the conveyance thereof by the workpiece conveying devices; an evaluating device receiving, from the scanning device, signals representing the actual lengths of the workpieces; and a length correcting device receiving, from the evaluating device, signals representing correctional values and for varying the length of the workpieces at a location between the roller pairs as a function of the correctional values. A heat treatment device heats the running band to a temperature sufficient to maintain the band in a red-hot state at the length-correcting location.
