Abstract
A pouring method and a pouring plant are described. Mould sections (15) are produced piecewise with cavities at two opposite ends thereof. The mold sections are combined in a line (15A-15D), wherein the cavities define a mold cavity (15a) having an exposed pour cup (30). The line of mold sections is advanced incrementally by drive means (16, 162) through an increment length that corresponds to the length of the mold sections (15), to and through a molding station (50). The true lengths of the produced sections (15) are measured and registered. The difference in length between the first mold section (15D) in the line (15A-15D) that lies immediately upstream of a pour cup (30), where a pouring operation was last carried out, and the last mold section (15A) in the line is calculated. The pouring machine (20) is moved from its latest pouring position along the line through a distance corresponding to this length difference while the line (15A-15D) is advanced towards the pouring station (50) to an end position (18) of the line advancing means (16, 162).
