FIELD: process engineering.SUBSTANCE: feeder chute has open container composed by central part of permanent section over its entire length and connected at every end with end part. It is made from plastic material by extrusion or pultrusion. Said chute has bottom connecting two lateral walls terminated in free ends, one of the latter being provided with protective section while outer zone of one free ends features larger cross-section than other part of said lateral wall. Protective section has slit and inner cross-section corresponding to that of larger edge zone of lateral wall but exceeds it a bit, while section width corresponds to lateral wall depth in boundary zone adjoining that with larger cross-section but exceeds it to cover said increased end zone. Said protective section is made of metal while edge zone has through cavity extending in lengthwise direction.EFFECT: higher strength, simple assembly/disassembly and transportation.11 cl, 5 dwg |
