Abstract
A plate width adjusting apparatus 1 for adjusting a strip 53 for a predetermined plate width, which is installed on a production line for the strip 53, is provided with bridle rolls 2 and 3. The bridle rolls 2 and 3 give tension in the transfer direction to the strip 53 being transferred on the production line to elongate the strip 53 in the transfer direction, by which the plate width of the strip 53 is adjusted.
Claims8
A plate width adjusting apparatus for adjusting a strip for a predetermined plate width, which is installed on a production line for said strip, comprising:
- elongating means for elongating said strip being transferred on said production line in the transfer direction of said strip;
- and
- means for controlling the elongation of said strip in the transfer direction by using said elongating means and controlling shrinkage in the width direction in order to adjust said plate width to a specified value,
- wherein said elongating means comprises tension generating means for giving tension in the transfer direction to said strip being transferred and bending means for giving bending force to said strip having been given said tension.
A plate width adjusting method for adjusting a strip for a predetermined plate width on a production line for said strip, comprising the steps of:
- elongating said strip being transferred on said production line in the transfer direction of said strip;
- and
- shrinking said strip in the width direction by means of the elongation of said strip, in order to adjust said plate width to a specified value,
- wherein said strip is elongated by giving tension in the transfer direction to said strip being transferred and by giving bending force to said strip having been given said tension.
A plate width adjusting apparatus for adjusting a strip for a predetermined plate width, which is installed on a production line for said strip, comprising:
- elongating means for elongating said strip being transferred on said production line in the transfer direction of said strip, said elongating means comprising tension generating means for giving tension in the transfer direction to said strip being transferred and bending means for giving bending force to said strip under tension by said tension generating means;
- means for controlling the elongation of said strip in the transfer direction using said tension generating means and said bending means, and adjusting shrinkage in the width direction by controlling said tension and bending force in order to adjust said plate width to a specified value;
- cutting means for cutting edges of said strip, which is installed on the downstream side of the installation position of said detecting means in the transfer direction;
- and
- cutting control means for, in the case where said strip has a portion in which a high tension cannot be applied, causing said cutting means to perform a cutting operation on said portion in order to continuously adjust said plate width to said specified value.
