Abstract
A roll forming apparatus incorporates tension rolls which feed a material along a longitudinal direction thereof. The tension rolls are arranged at predetermined intervals and are driven. Also, forming rolls which form the fed material are arranged alternatingly on both sides in the width direction of the material between adjacent tension rolls. The roll forming apparatus described above prevents scratches on the material from forming as a result of the material sliding on the forming rolls.
Claims15
A roll forming apparatus comprising:
- tension rolls for feeding a material along a longitudinal direction thereof, said tension rolls being arranged at predetermined intervals and being driven;
- and a plurality of forming rolls for forming said material, said plurality of forming rolls being arranged on both sides of said material in a width direction and along a feeding direction of said material, each of said plurality of forming rolls further being positioned between adjacent tension rollers, wherein
- said plurality of forming rolls are alternatingly positioned along the feeding direction of said material relative to each other such that a first one of said forming rolls is positioned between a first set of adjacent tension rolls along a first side of said material, with a subsequent forming roll being positioned along a second side of said material and between a set of adjacent tension rolls subsequent to said first set of adjacent tension rolls whereby only one side of said material between a set of adjacent tension rolls is formed by corresponding forming rolls.
