Abstract
PURPOSE:To make the pitch of links of a link work variable in a heat treatment section and at the same time the exchange of sprockets unnecessary by a method wherein a link pitch releasing section is provided for the link work, which has passed through the heat treatment section of a sheet-like material after being biaxially stretched. CONSTITUTION:A link work 3 consists of outside links 12 and 13 and inside links 14 and 15, both end parts of which are connected with link shafts 16a and 16b in the form of a folding scale and the link shaft 16b engages with sprockets 7, 8 and 9 and bearing rollers 17 and 18 roll along grooves, which are respectively made by guide rails 4 and 6 and 4 and 5. The pitch of rollers of a roller chains 19 is determined by being regulated with the rails 4, 5 and 6 and at the same time the pitch of clippers 2 is also determined. A sheet-like material 1, which is stretched in a stretching section E by changing the pitch of the clippers from P1 to P2, is contracted in a contracting section J by chang ing the pitch of the clippers to P3 and passed through a cooling section K and finally released in a section G from the clippers 2. The pitch of the link work becomes again back to P2 in a link pitch releasing section R so as to engage the link shaft with the sprocket 9.
