Abstract

Dispositivo di comando a passo (10) per la propulsione di una slitta a spostamento longitudinale (26) in base ad una legge del moto prestabilita, con un rullo cilindrico esteso (20), sistemato vicino alla slitta a spostamento longitudinale e fisso con il suo asse longitudinale centrale parallelamente alla direzione di avanzamento della slitta, però girevole motoricamente, nella cui superficie cilindrica tangenziale è ricavata una scanalatura di pilotaggio (22) con un decorso conforme alla legge del moto desiderata, nella quale scanalatura ingrana in modo appropriato la estremità libera di un perno di trascinamento (28) che sporge verso il rullo cilindrico (28). Il perno (28) è sorretto rigido in un supporto (32), alloggiato spostabile a sua volta nella o sulla slitta (26) di una corsa limitata in direzione della corsa slitta. Il supporto (32) rispetto alla slitta (26) risulta precaricato elasticamente in una posizione di trascinamento nominale, dalla quale è spostabile con aumento del precarico elastico durante lo spostamento della slitta (26) verso un pezzo oppure un arresto nella zona preselezionata dalla corsa di spostamento limitata.(Fig. 1)
