MOULDING OF CONTAINERS Russian patent published in 2009 - IPC B29C51/02 B29C49/02 

FIELD: containers.

SUBSTANCE: method for moulding of stock from plastic material includes expansion of stock for production of container. At that moulding includes pressing of stock in moulding facilities, in which its expansion takes place. Method includes stock expansion in moulding facilities for production of container. Prior to expansion of stock plastic material portion is moulded in paste-like condition in moulding facilities for stock production. Device for stock moulding comprises moulding facilities, forming facilities for stock expansion in moulding facilities and support facilities. The latter interact with forming facilities. At that forming facilities and support facilities create configuration, in which forming facilities and support facilities interact with each other in order to limit forming unit for pressing of half-finished product from plastic material to produce stock. They also create additional configuration, in which forming facilities and support facilities interact with each other in order to limit block for expansion of stock for container production.

EFFECT: technical result achieved during application of method and device according to invention, consists in the fact that conditions are improved for moulding of semi-finished product installed near opening of moulding die for moulding of containers and creation of more compact systems for containers production by blowing.
