FIELD: electricity.
SUBSTANCE: invention relates to the method and device of laser perforation of the multilayer roll materials, and is intended, in particular, for use in space engineering to manufacture screen-vacuum thermal insulation of the space vehicles. Tension of the perforated layer of the roll materials is set individually for each layer depending on the material and structure. Initially the perforated layers of the material are subjected to ionisation radiation creating at the adjacent layers of the opposite electrostatic charges. After perforation polarity and residual electrostatic charge are determined on the manufactured multilayer roll material, and parameters of the ionisation radiation are determined to neutralise the residual electrostatic charge. Its neutralisation is performed by action on the multilayer material by the neutralising ionisation radiation.
EFFECT: invention use increases quality of the perforated roll materials and capacity of the process.
