Title: Carrying method for long metallic pipe or the like
Inventor: HATA RYOSUKE
IPC: B21C47/24
Filed: 1987-06-05
Abstract: PURPOSE:To lessen the diameter of a drum and to increase the number of turns by laying a vertical welding seam horizontally at about 90 deg. to the side on which metallic pipes wound to the drum are in contact with the barrel of a drum when corrugated pipes are carried. CONSTITUTION:The corrugated metallic pipes 2 are wound around the drum as its vertical welding seam 3 is kept horizontally at about 90 deg. to the side on which the metallic pipes 2 are in contact with the barrel 11 of the drum 1. Accordingly, since the welding seam 3 is located at a section wherein the pitch of the corrugation is unchangeable even when the corrugated metallic pipes 2 are bent, it is nearly free from the influence of bending. Therefore, the diameter of the drum at the time of carrying can be reduced to the diameter of the drum satisfying the intrinsic bending characteristics of the corrugated pipes without welding seam. As a result, if outer diameters are equal in drums, the winding capacity is increased and the number of turns and carrying length can be also increased.

Abstract: PURPOSE:To obtain wide amorphous metal ribbons having a good surface roughness, by combining the two sets of quenched forming roll in single roll process, while keeping the different rotating direction, to form a rolling part and overlapping the edge parts of amorphous metal ribbons formed by each roll. CONSTITUTION:Quenched forming rolls 6 and 7 of single roll process are arranged in parallel and closely to each other so that they may have different rotating directions, respectively, and rolling section 5 is formed at the space between the rolls.
