Abstract: The invention relates to a reciprocating process and apparatus for laying profile pieces on a base in view of plotting and/or cutting off.The process is characterized by the fact that it comprises the storage into a computer unit (1) of the coordinates of templates, shapes, patterns for cutting out, after the positioning of the base on a plotting or cutting table, the direct or indirect projection on the surface of said base of one or more images of said stored templates, shapes or patterns by means of suitable videoprojection means (2 thru 4), the positioning at will of the image or images on the surface of the base, after the optimum positioning has been achieved, the memorizing of the position data of said images and, on the basis of said data, the command to plot on the base and/or to cut out thereof.Major applications: with the leather and textile industries.

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.
