FIELD: personal use articles. ^ SUBSTANCE: invention relates to shoe industry. Device to moisten shoe upper stocks with controlled volume of working chamber, comprising loading compartment arranged in the form of reservoir with tightly closing door and arranged between vacuum chambers that are connected by their ends to loading ends of chambers. Inside compartment there is a cover freely installed and arranged as a piston, which may move along vertical axis along guides, covering loading ends of chambers one by one. Vacuum chambers are connected to vacuum pump and have holes to supply working agent. Depending on required additional weight of moisture, upper chamber serves as working one or as an extension of a lower one as cover-piston is moved up along guides and its fixation in required position, which makes it possible to moisten large quantity of shoe upper stocks. Invention objective: to improve device for moistening of shoe upper stocks by control of working chamber volume. ^ EFFECT: invention makes it possible to simultaneously process larger quantity of shoe upper stocks by control of working chamber volume. ^ 1 dwg |
