Title:

A STATIONARY BLOW-MOULDING MACHINE AND METHOD FOR FORMING PREFORMS

Document Type and Number:

WIPO Patent Application WO/2017/194624

Kind Code:

A3

Abstract:

The invention relates to a device (1) for forming plastic preforms (10) into plastic containers (20), comprising a conveying device (2) that conveys plastic preforms (10) along a predetermined conveyor path (P), and at least one forming station (4) arranged to be stationary on said conveyor path (P), wherein said forming station has a blow mould (12) that can be opened and closed and which forms a cavity when in a closed state inside of which the plastic preforms (10) can be formed into the plastic containers (20) by applying a gaseous medium, said forming station comprising a closing unit (6) for closing the blow mould (12), and this closing unit (6) comprising at least one component (12a) of the blow mould (12) which can move relative to another component (12b) of the blow mould (12), wherein the forming station (4) also comprises an application device (42) that can be placed on a region of the plastic preforms and/or the blow moulds in order to apply the gaseous medium to said plastic preforms (10). The claimed device also comprises a valve unit (40) for controlling the supply of the gaseous medium to be supplied to the plastic preforms (10). According to the invention, the closing unit (6) comprises a wall (30) that at least partially surrounds the blow mould (12) in a peripheral direction, and said valve unit (40) is arranged within this wall (30).
