Abstract

Shoes with bonded type soles may be made at a higher rate of speed on a line with continuous travel of the lasts, at a predetermined and variable rate, where the series of automatic machines come, in most cases, to work on the last. Either a complete installation, with automatic, programmed cycle, or a series of automated units particularly make possible: placing of the insoles on the last with foot and size selection and centering of the insoles; simultaneous gluing and assembly of the sides after placing of the uppers; roughing operations with preregistration of the depth and following of the profile of the sides; overturning of the sole, prepositioning on the upper, reactivation of the glue, attachment and bonding of the sole; and removal from the last. The installation may be used for the production of various types of shoes by units assembled by unit in pairs or by pairs.
