Patent ID: 7775248

Claim:
A system comprising: a supply roll of a laminate; a mandrel for wrapping said laminate therearound; feed rollers that spool said laminate off said supply roll onto said mandrel, said feed rollers being attached to a mounting plate by an adjustable bracket that sets an angle of said laminate with respect to said mandrel, adjacent windings of said laminate-being joined to one another at overlaps thereof, wherein each winding of said laminate makes at least one complete revolution around said mandrel before said laminate advances to its next adjacent winding so as to form a gas seal at the overlaps of the adjacent windings; and a cutting station adapted to cut cylindrical tubes formed by windings of said laminate about said mandrel, wherein said cutting station comprises: a motor that drives a drive wheel; a cutting wheel; a plurality of cutting blades disposed in channels formed in said cutting wheel; and a solenoid operatively connected to said cutting wheel, wherein before cutting said cutting wheel turns together with said drive wheel and said cutting blades do not contact said laminate, and said solenoid is operative to arrest rotational movement of said cutting wheel so as to impart a centripetal force on said cutting blades, thereby thrusting them to contact and cut said laminate.
