Abstract

The invention relates to the field of cloth pleating machines, and in particular, to a pleating machine for pleating cloth with mutually converging folds. The technical problem to be solved was that of providing a pleating machine which could also work accurately and reliably on highly flabby and/or hard-to-fold fabrics. The problem has been solved by providing a pleating machine having an angularly oscillating arm and an abutment wall for said arm, which are configured comb-like to be mutually interleaved, and provided with control and guiding devices for said wall which are operative to drive the same through a cyclic oscillation along a closed path causing said wall to move from a position close against a cloth to be pleated to one of insertion in said arm over and past a cloth flap which has been folded by said arm.

Dependent claims

A pleating machine for pleating cloth with mutually converging folds, comprising:

a working platform, an angularly oscillating entrainment arm on said platform adapted to impart a cloth placed on said platform with a step-like forward movement, a lifting abutment wall adapted to contact said cloth adjacently a travel limit position of said arm, and guide members effective to guide pleated cloth and being located adjacent said wall on the opposite side to said arm, characterized in that said abutment wall and said arm are both configured comb-like at least in part so as to be mutually interleaved, and in that control and guiding devices are provided for said abutment wall to be subjected to cyclic oscillation along a path leading said abutment wall to an inserted position in said arm after moving over and past a cloth flap which has been folded over by said arm and effective to then press said flap against said guiding members for the pleated cloth.
