FIELD: personal use articles.SUBSTANCE: invention solves the task to manufacture a broom without additional assembly in a single operation; in particular, onto laid out twigs of polymer materials one immediately casts the hood with a hole for the broom handle by way of casting under pressure in a press-mould; the broom polymer twigs are laid out on the lower semi-matrix of the press-mould, limited by the rest and clamped with a rubber ring; the upper semi-matrix of the press-mould is installed over the prepared twigs of polymer material; during the two semi-matrices connection the broom pouring with simultaneous hood formation takes place.EFFECT: broom manufacture labour intensity reduction and the broom prime cost reduction due to exclusion of the operation of the broom brush base assembly. |
