Abstract
A method and a device for the manufacture of plastic packagings, the same being manufactured by stretch blowing a bottle-like preliminary packaging which is, after completion, treated by means of a laser and thus reshaped to the final packaging. Also, a plastic container manufactured according to this method and with this device.
Claims36
Method for the manufacture of a plurality of plastic packagings, comprising:
- providing a heated preform, shaping a preform to a preliminary packaging, removing an upper part of the packaging of this preliminary packaging in a cutting module wherein in removing the upper part of the packaging of the preliminary packaging at least one laser cutting unit performs a cutting operation on the preliminary packaging, and wherein several of the preliminary packagings are simultaneously and respectively treated with one laser cutting unit each, and moving the preliminary packagings as well as the laser cutting units on an essentially circular conveyor track during the cutting operation, wherein the laser cutting units stand still while laser beams move along the conveyor track such that a relative stand still between the laser beam and the preliminary packaging is generated during cutting, and splitting up a laser beam by a centrally arranged distributions node to the various laser cutting units during cutting.
Device for the manufacture of plastic packagings, comprising a heater for preforms, a blowing machine for the manufacture of a preliminary packaging , and a cutting module comprising a laser cutting module with at least two laser cutting units mounted on a rotary container table wherein a laser is provided, of which the laser beam can be split up to the various laser cutting units by a centrally arranged distributions node such that a relative stand still between the laser beam and the preliminary packaging can be generated during cutting, and wherein the laser cutting units are attached radially between the distribution node and the preliminary packagings to be cut.
