Abstract

PURPOSE:To make it possible to give minute linear strain continuously, by installing strain-giving rolls rotated by running force of steel plate and having buried steel balls in its grooves formed on the outer circumference, and a receiving roll which is synchronized with the strain-giving roll in shifting speed, and by constructing them so that strains will be given to steel plates by means of the pressing force of steel balls. CONSTITUTION:Steel plate 1 supplied from uncoiler 6 is coiled round coiler 7 by means of guide roll 2 driven by motor 4 through spaces between receiving roll 5 and strain-giving rolls A and B and guide roll 8 and roll 5. When the steel plate is coiled round coiler 7, motor 4 is stopped and the steel plate is pulled by coiler 7. Each above-mentioned roll is rotated by the running force of steel plate and roll 5 and rolls A and B have a common rotary speed mechanism (gears 9, 10 and 11) and plural steel balls 23 and 38 are buried in each of plural grooves 22 and 24 installed in parallel with an optional interval in the longitudinal direction on the outer circumference of strain-giving rolls A and B. The strain-giving rolls is moved freely in its radius direction by a constant pressing force, and by the pressing force of steel ball, strain lines of a constant interval are continuously given to steel plate 1 efficiently.
