An apparatus for serially making formed parts from a web of deformable material having a plurality of progressive die forming stations for forming multiple parts from the web by advancing the web through each forming station. In one embodiment, the apparatus has a control system for measuring parts formed in the apparatus and adjusting the relationship between first and second die portions of the apparatus to keep the parts formed in the apparatus within predetermined specifications.

[ The embodiments for which an exclusive property or privilege is claimed are defined as follows:] [1.] An improved apparatus for serially making formed parts with at least one measurable dimension from a web of deformable material comprising:a plurality of progressive die forming stations for forming multiple parts from the web by advancing the web through each forming station including a first die and a second die reciprocally movable with respect to the first die between a retracted position and a deforming position;a cutting station for severing the web after the web has passed through the die forming stations to separate the formed individual parts from the web;the improvement comprising:an adjustment assembly associated with at least one of the first and second dies for changing the dimensional relationship between the first and second dies in the deforming position;an actuator interconnected with the adjustment assembly and responsive to a first signal for operating the adjustment assembly; anda position sensor adapted to contact a part which has at least been partially formed and measure the at least one measurable dimension and to generate the first signal responsive to the measured dimension;whereby the adjustment assembly can change the dimensional relationship between the first and second dies responsive to the signal from the actuator.
