Estimating the term…
A method for applying pressure relief valves to packaging during the packaging process. A punch shaft and an applicator shaft each have an axis and opposed ends. The punch shaft has a punch at one end. The applicator shaft has an applicator vacuum head at one end. Each shaft moves axially between retracted and extended positions. The shafts are angled, with the punch and applicator ends more apart than the respective opposed ends, and are carried on a plate for limited rotational movement relative to the applicator unit. First the punch is pivoted from a first position into a third position, while the applicator head is simultaneously pivoted from a second position into the first position. Then the punch is pivoted from the third position back into the first position, and the applicator head is simultaneously pivoted from the first position back into the second position.
A method for applying a pressure relief valve to packaging during the packaging process comprising the steps of:
The method of claim 18 for applying a pressure relief valve to packaging during the packaging process additionally comprising the step of rotating a plate carrying the punch and the applicator vacuum head between only two positions, a piercing position and a valve applying position.
The method of claim 18 for applying a pressure relief valve to packaging during the packaging process further comprising the step of releasing the vacuum of the applicator vacuum during the step of putting the pressure relief valve on the package.
