US 6,371,400 B1 · Band steel plate winding apparatus

Abstract

A band steel plate winding apparatus comprises a winding drum for winding a band steel plate; unit rolls, and curved surface guides adjacent to the unit rolls, provided along a circumferential surface of the winding drum forwardly and backwardly movably between a winding drum surrounding position and a retreat position, the position of the unit roll relative to the winding drum at the time of entry of the band steel plate being downstream at an angle of about 15 degrees or less from the position of contact between the winding drum and the band steel plate; and ejection nozzles provided in a guide surface of each of the curved surface guides for ejecting a gaseous or liquid fluid at a high speed toward the band steel plate before the band steel plate collides with the curved surface guide. The band steel plate winding apparatus permits high speed winding of a band steel plate while effectively preventing buckling of a front end of the band steel plate, and can avoid a great increase in equipment cost.
