components 2 on thecarriage 41 have been machined,carriage 41 is moved from its working position and replaced with anew carriage 41 loaded withnew components 2 to be machined. - Machine 1 has some advantages mainly deriving from the
carriage 41 being relatively simple and cost-effective, being free from motors, being capable of stocking a relatively high number ofcomponents 2, ensuring a relatively high production autonomy to machine 1, and implying a relatively low presence of operating personnel. - According to some variants (not shown):
- the
feeding assembly 25 is eliminated and thecomponents 2 are directly transferred between the gripping andconveying assembly 15 and thelifting device 37; - the
feeding assembly 25 is eliminated, thecomponents 2 to be machined are directly transferred fromcarriage 41 to the gripping and conveyingassembly 15 by means of thelifting device 37, and the newly machinedcomponents 2 are directly transferred from theassembly 15 to a further carriage entirely similar to thecarriage 41 either by means of thesame device 37 or by means of a further lifting device entirely similar to thedevice 37 itself; and - the
feeding assembly 25 is eliminated and replaced by two feeding assemblies, which have each a single resting plane, are arranged on opposite sides of thebase 3 in thedirection 4 or are reciprocally aligned in thedirection 9, and cooperate each with acorresponding lifting device 37 and acorresponding carriage 41, and therefore are used one to feed thecomponents 2 to be machined to the gripping and conveyingassembly 15 and the other is used to receive the newly machinedcomponents 2 from theassembly 15 itself.
