Abstract
A process and a device for the manufacture of hollow plastic bodies, particularly of plastic bottles, in which plastic molding blanks are guided, by means of a shuttle system with at least one guide rail, through a tempering station, and are brought to a temperature which is suitable for extension blowing, whereby the plastic molding blanks are turned in their spatial orientation, by means of the shuttle system, through the twisting or curving of the at least one guide rail along the transport path.
Claims22
A device for the manufacture of hollow plastic bodies comprising a transport device to help guide plastic molding blanks (1) by a transfer station (29) through a tempering station to an extension blowing station, said transport device comprising at least one guide rail (17, 18) forming a stationary closed loop path, discrete slide units (44) with holding devices for plastic molding blanks (1) slideable individually within and supported by said at least one guide rail, a drive unit adapted to push the discrete slide units along the at least one guide rail, and a first twisting area of said at least one guide rail (17, 18), whereby at least one change of orientation of the spatial position of the plastic molding blanks is carried out by means of the first twisting area of the at least one guide rail.
