Abstract
In tack seat lasting machines, operator skill is often required because of irregularities in last manufacture, especially in drilling the last pin hole. Thus, automatic presentation is difficult. In accordance with the invention the last pin (32') is mounted for limited rocking movement about an axis extending lengthwise of the shoe bottom, and shoe centralizing means (424) engages edges of the shoe, at opposite sides of the last pin, to ensure alignment with a longitudinal center line of the machine. The centralized shoe is then clamped by a holddown (406), the centralizing means released, and the shoe heel end clamped by a heel band (520) which, by equalized pressure being applied to both "legs" thereof, holds, the shoe in position as presented.
