Abstract
The machine allows filling of internally sterile plastic bags with any liquid and sealing them. The machine comprises: liquid-proportioning apparatus (1), jaws (17, 18) suitable for pneumatically holding the upper lips of the bag to be able to open, fill, close it by heat-sealing (jaws 7, 8). The most important part of the machine consists of devices (10, 11, 12) able to control the jaws to open the bag with cosinusoidal law acceleration, slowly at first, preventing detachment of the upper lips of the bag during opening, and then rapidly operating so as not to delay the successive operations of: closing, sealing and discharging of the filled bag. These devices consist of a toggle-joint lever system. They make possible a notable daily production of filled and heat-sealed bags with a single proportioning and heat-sealing station, or with a limited number of stations.
