Abstract
An automatic system for forming custon-made shoe inserts for a person's feet from a pair of blanks is provided with a foot impression mechanism including a pair of pin arrays for simultaneously forming an impression of the contour of the undersurface of each of the person's feet and for releasably retaining each impression formed. Each of the pin arrays is arranged in orthogonal rows and columns with adjoining pins in each column having asymmetric contacting surfaces. The system is also provided with a blank holding assembly for holding the blanks in lateral alignment with the impressions, a blank shaping mechanism for successively sensing each impression and for concomitantly successively cutting material away from each blank in conformance with the corresponding sensed impression, and a drive mechanism for automatically driving the blank shaping mechanism both laterally and to-and-from over the impressions and the blanks in response to a single drive motor so as to automatically form the custom-made shoe inserts from the blanks in conformance with the impressions. A sensing and switching unit automatically stops the drive mechanism when the blank shaping mechanism is in both a de…
