Abstract

Continuous drawing method and device (10) straight drawing operations, whereby the drawing is carried out with a pair of tracked or chain means (12-112) that bear drawing clamps (15-115), the tracked or chain means (12-112) comprising means (17-18-19) to adjust the distance between centres of the tracked or chain means (12-112) in relation to a drawing axis (13) so as to adapt that distance to the various drawing diameters, the adjustment of the distance between centres of the tracked or chain means (12-112) and the final clamping of the material being drawn between the drawing clamps (15-115) taking place in at least two working steps, the first of these at least two steps providing for the approach of the tracked or chain means (12-112) to the drawing axis (13) with substantially mechanical methods and advantageously bringing one of the two tracked or chain means (12-112) to its final drawing position, whereas the other tracked or chain means (12-112) is halted at a position separated by a desired amount from its final position, while the second of at least two steps arranges for the final positioning of that other tracked or chain means (12-112) by means of an actuation with a fluid. The device (10) comprising the following working units: first displacement means (21-121) connected to the means (17-18-19) that adjust the distance between centres, second displacement means (22-122) slidably coupled to the first displacement means (21-121) and connected to their respective tracked or chain means (12-112), and a chamber (23) to hold fluid, which is positioned between the first (21-121) and second (22-122) displacement means and can be filled momentarily with fluid under pressure. l
