PLANT FOR PRODUCTION OF POLYMER SHEETS Russian patent published in 2011 - IPC B29C39/02 

FIELD: process engineering.

SUBSTANCE: invention relates to equipment intended for producing polymer sheets, particularly, organic glass sheets from monomers and prepolymers in polymerisation moulds. Proposed plant comprises, at least, one set of polymerisation moulds. Said molds are made up of heat conducting plates arranged in parallel, moulding substrates secured on said plates and polymerisation mould seals arranged between moulding substrates along their edges. Plant comprises also appliances to joint set elements together, heat conducting plate heating and cooling system, system to feed polymerisation stock into polymerisation moulds. Each plate is embraced by clip-like frame with its ends articulated with plate side faces. Cartridges with rolls fitted therein are arranged on clip crosspiece ends. Rolls rest on horizontal guides arranged above the set. Plant comprises also an appliance to drive rolls along horizontal guides. Said appliance comprises two parallel branches of chains arranged above horizontal guides. Chins interact with set of sprockets driven by electric reversing drive. Each chain is provided with carriage with push tooth secured thereto, while wall of each cartridge is jointed to the frame of push tooth passage opening. Frame top part represents a locking bell crank arm articulated with the set of levers and drive to up or down bell crank locking arm.

EFFECT: accelerated and simplified process.
