Method and apparatus for volume apportionment of and distributing a quantity of pasty material

摘要

Method and apparatus for apportionment includes compressing a paste in an apportioning chamber and thereafter delivering the paste towards a nipple after opening of a blocking element, the volume apportioning of the amount of paste to be distributed being undertaken by measuring the displacement of a piston in the apportioning chamber during delivery. The method and apparatus ensure that the apportioning chamber is placed under low pressure so as to facilitate introduction of the paste and delivery of the paste at a fast speed and then at a slow speed.
