Abstract

<PICT:0969655/C1/1> In a process for manufacturing sheets, plates, tubes &c., with walls having at least partly a net-like structure, synthetic or other plastic material is extruded through a slot of uniform width whilst the outlet of the slot is stopped at suitable places and times to obtain the required net-like structure. A flat synthetic resin sheet having rectangular apertures is formed by reciprocating a comb-shaped plate 3 across the outlet of the die 1 through which the sheet is extruded. The plate 3 reciprocates between a position in which its teeth partially obstruct the die outlet, when vertical elements 6 are extruded, and a position clear of the die outlet when horizontal elements 8 are extruded. In further embodiments (a) the comb is in the form of a slotted plate having teeth on each side of the slot, the two sets of teeth either being spaced apart or interengaging; (b) a tube is extruded between a fixed mandrel and a surrounding annular die having a notched surface and reciprocable axially to engage the mandrel so that extrusion takes place alternately through the notches and through an annular gap between the mandrel and the die; (c) a tube of circular or rectangular cross-section is extruded as in (b) but between a movable mandrel and a fixed outer die; (d) a tube having a surface with a net-like pattern is extruded by a modification of method (b) or (c); (e) two bar-like die elements having transverse die parts are reciprocated towards and away from each other to form a net having rectangular meshes or a sheet or plate having a rectangular net-like surface pattern or ribs. The extruded material may consist of thermoplastic and thermosetting synthetic resins, natural and synthetic rubbers, viscose, glass, and metals and alloys in pasty or molten state. The extrusion of metals and alloys may be effected through a train of rolls.
