METHOD OF PRODUCTION OF DRAWN SECTIONS AND TUBULAR DRAWN SECTIONS Russian patent published in 1997 - IPC

FIELD: production of drawn sections and tubular drawn sections with a filled core by the straight-line flow method. SUBSTANCE: filler for moulding of the core of these sections is fed through a hollow moulding member, and fabric for moulding of the section shell is fed over the external surface of the moulding member to the moulding device, sections impregnated with resin are mould and drawn out of the outlet. The moulding member and moulding device are installed vertically in the same axis. Fabric for moulding the shell is fed over the external surface of the moulding member from top to bottom. The filler for moulding the section core is passed through a vibrating screen installed in the upper part of the moulding member for uniform distribution of the filler over the entire cross-section area of the drawn section. At production of tubular drawn sections fabric for forming the external and internal shells is fed over the external surfaces of the moulding member and mandrel installed in it; filler for moulding the core of the tubular drawn section is fed through the annular space formed by the moulding member and fabric for forming the internal shell to the moulding device of tubular drawn section; the tubular drawn section impregnated with resin is drawn out of the moulding device outlet. The moulding member and moulding device are installed vertically in the same axis. Fabric for forming the external and internal shells is fed over the external surfaces of the moulding member and mandrel from top to bottom. EFFECT: facilitated procedure. 3 cl, 6 dwg
