PROGRAMMABLE CONCENTRIC HEAD FOR THE APPLICATION OF LIQUID TO LIDS OF DIFFERENT SHAPES

摘要

The invention is used for the application of a liquid fluid to a peripheral area of a lid by means of pistols for injecting said liquid fluid. It comprises an articulated mechanical device (56) combined with at least two coaxial tubular shafts: a main supply shaft (12) and a lower shaft (10b); where a lower end of the main supply shaft (12) connects to a first part of the articulated mechanical device (56), while a second part of the articulated mechanical device (56) connects to a lower end of the lower shaft (10b). The two coaxial tubular shafts (10b) (12) rotate independently by means of transmission devices. The main supply shaft (12) is arranged in the inner hole of the lower shaft (10b), which is arranged coaxially around at least one section of the main supply shaft (12).
