Abstract
Abstract An apparatus for incising an advancing glass web passed continuously upon horizontal transporter means. The apparatus comprises a beam extending across the web and defining a closed loop path, upon which a carriage having incising tools is movably supported. An elongated coil, subdivided into different sections independently energizable to generate respective section eddy currents is fixed along the beam. Eddy currents are generated in part of the carriage, and the motion of the carriage derives from the reaction between magnetic fields of the carriage and the coils. The carriage is deviable toward and away from the glass web during its movement around the beam, so that the incising tool is lowered on to the glass web during the incision stroke and lifted therefrom on its return stroke.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
227 words
An apparatus for incising an advancing glass web, comprising: a beam extending across the glass web defining a closed loop path; a carriage movably supported on the beam, deviable toward and away from the glass web during its movement along the closed loop path, having at least an incising tool at one end and at least an armature plate at the opposite end, said incising tool being engageable with said glass web for performing an incision stroke on a first run, across the glass web and disengageable from said glass web during a second run back across the glass web; closed loop means fixed upon the beam for supporting the carriage; means for driving the carriage upon said closed loop means, said means being formed by a closed circuit extending across the glass web having an elongated coil, running parallel to said closed loop means and divided into sections independently energizable, to generate respective section eddy currents, and an endless belt loop running parallel to the coil, carrying coupling plates arranged to lie parallel between the armature plate and the coil, said coil being adapted to generate eddy currents upon energization of the coil section, adjacent the carriage so that the armature plate is magnetically coupled to the coupling plate to move the carriage at substantially the same speed as the belt loop, during the incising run.
Claim 2
Independent Claim
227 words
An apparatus for incising an advancing glass web, comprising: a beam extending across the glass web defining a closed loop path; a carriage movably supported on the beam, deviable toward and away from the glass web during its movement along the closed loop path, having at least an incising tool at one end and at least an armature plate at the opposite end, said incising tool being engageable with said glass web for performing an incision stroke on a first run, across the glass web and disengageable from said glass web during a second run back across the glass web; closed loop means fixed upon the beam for supporting the carriage; means for driving the carriage upon said closed loop means, said means being formed by a closed circuit extending across the glass web having an elongated coil, running parallel to said closed loop means and divided into sections independently energizable, to generate respective section eddy currents, and an endless belt loop running parallel to the coil, carrying coupling plates arranged to lie parallel between the armature plate and the coil, said coil being adapted to generate eddy currents upon energization of the coil section, adjacent the carriage so that the armature plate is magnetically coupled to the coupling plate to move the carriage at substantially the same speed as the belt loop, during the incising run.
Claim 3
Dependent Claim
33 words
The apparatus as defined in claim 10, wherein the carriage is movable around the closed loop means extending across the glass web and performing the first and second runs on opposite loop sides.
Claim 4
Dependent Claim
19 words
The apparatus as defined in claim 11, wherein the closed loop means comprises a guide rail supporting the carriage.
Claim 5
Dependent Claim
35 words
The apparatus as defined in claim 10, wherein the endless belt loop comprises a chain movable in a continuous motion along the closed circuit, at a speed dependent upon that of the advancing glass web.
Claim 6
Dependent Claim
46 words
The apparatus as defined in claim 12, wherein the guide rail lies in a plane inclined to that of the advancing glass web so that the incision tool is lowered on to the glass web for the incision stroke and lifted therefrom on its return stroke.
Claim 7
Dependent Claim
107 words
The apparatus as defined in claim 10, wherein the elongated coil comprises, a first section whose length is substantially equal to the length of the carriage and which provides a starting station, a second section comprising a straight out run along the beam from the starting station; a 180* turn section at one end of the beam, and a straight return back along the beam; a third section comprising a 180* turn section at the opposite end of the beam providing a deceleration station between the return run, and a fourth section which is a low voltage section for feeding the carriage on to the starting station.
Claim 8
Dependent Claim
96 words
The apparatus as defined in claim 10, wherein the carriage is one of a set of carriages mounted in series on the beam and successively movable along the closed loop path, each carriage having an incision tool and an armature plate aligned upon the closed circuit, each carriage being adapted to be set upon an incision run by a command signal when it finds itself at a point of the circuit defining the starting point, and being adapted to follow a preceding carriage for performing a line of incision distinct from that of the preceding carriage.
