METHOD FOR PRODUCING A WINDING DEVICE AS WELL AS WINDING DEVICE

摘要

A method for producing a winding device for interconnected slats of a roller shutter, in which a sheet of metal having a pre-determinable length, width and thickness will be provided, seen over the length of the sheet of metal, with an eyelet formed out of the sheet of metal, and the sheet of metal, seen over the length of the sheet of metal, will be bent into the circumferential direction such that a contour is formed that differs from the cylindrical shape and the longitudinal edge of the sheet of metal, which is located opposite the eyelet, will take its bearing in the area of the eyelet, wherein, seen over the length of the sheet of metal, the marginal region of the longitudinal edge will be connected to the eyelet by welding.

主权项

1. A method for producing a winding device (4) for interconnected slats (15) of a roller shutter, in which a sheet of metal (1) having a pre-determinable length (l), width (b) and thickness (d) will be provided, seen over the length (l) of the sheet of metal (1), with an eyelet (5) formed out of the sheet of metal (1), and the sheet of metal (1), seen over the length (l) of the sheet of metal (1), will be bent into the circumferential direction such that a contour is formed that differs from the cylindrical shape and the longitudinal edge (3) of the sheet of metal (1), which is located opposite the eyelet (5) will take its bearing in the area of the eyelet (5), wherein, seen over the length (l) of the sheet of metal (1), the marginal region of the longitudinal edge (3) will be connected to the eyelet (5) by welding (10).
