A machine for drilling fragile sheet-like materials, in particular sheet glass or the like, of a type comprising a feed-in station (1) for a sheet blank (3) arranged to cooperate with a sheet blank drilling station (2), said feed-in station (1) including a frame (4), a means of moving said sheet blank (3) slidingly on said frame (4), and a position reference means (21-22) for said sheet blank (3), said sheet blank drilling station (2) including a frame (30) provided with a holding and locating means for drill units (31a,31b) overlying and underlying a working zone and adapted to interact with said sheet blank (3) at said working zone, characterized in that said slide means comprises a plurality of rollers (5) at least some whereof are driven by a motor unit (6) and provided with a means of combining a forward movement of said sheet blank (3) with an approaching movement of said sheet blank (3) toward an abutment member connected to said frame (4).
Claim 3
Dependent Claim
73 words
A machine according to Claim 1, characterized in that said rollers (5) define a surface of advancement for said sheet blank (3) and extend with their axes substantially crosswise to the direction of advancement of said sheet blank (3), said means of combining a forward movement of said sheet blank (3) with an approaching movement thereof comprising, on said rollers (5), a shroud (8) having ridges (9) with a helical pattern formed thereon.
Claim 4
Dependent Claim
23 words
A machine according to Claim 2, characterized in that said ridges (9) are formed from a high frictional coefficient material such as rubber.
Claim 5
Dependent Claim
38 words
A machine according to one or more of the preceding claims, characterized in that said position reference means (21-22) comprises a moveable pad element (21) located substantially orthogonally,relatively to the surface of advancement of said sheet blank (3).
Claim 6
Dependent Claim
67 words
A machine according to one or more of the preceding claims, wherein said drill units (31a,31b) comprise drilling heads (32,33,34,35) having pressure members (56) and being hydraulically connected to a cooling fluid supply, and characterized in that it comprises discharge conduits (58) for said fluid associated with each pressure member (56) and cooperating with a trough (59) adapted to direct said fluid away from said working zone.
Claim 7
Dependent Claim
47 words
A machine according to one or more of the preceding claims, characterized in that it comprises a puller chest (61) associated with each of the lower drilling heads (32,33,34,35) in said drill units (31a, 31b) and cooperating with a collecting chest (62) mounted on said frame (4).
Claim 8
Dependent Claim
