Abstract
A glass plate cutting machine 1 includes a cutter wheel 4 for forming a cut line 3 on a glass plate 2; a moving means 5 for moving the cutter wheel 4 along a cut line 3a which has been preset and is to be formed on the glass plate 2; a resiliently pressing device 6 for resiliently pressing the cutter wheel 4 against the glass plate 2; and a control unit 7 for controlling the resiliently pressing device 6 so as to alternately change over the intensity of a resiliently pressing force of that cutter wheel 4 with respect to the glass plate 2 in the movement of the cutter wheel 4 by the moving means 5.

1-8. (canceled)
A glass plate cutting method, comprising the steps of:
- moving a cutter blade along a cut line which has been preset and is to be formed on the glass plate, said cut line including a first cut line on the glass plate and a second cut line successively connected in series to the first cut line on the glass plate;
- and effecting for several times a cut line forming step of forming the cut line on the glass plate in the movement of said cutter blade, said cut line forming step having a first step of pressing the glass plate by said cutter blade with a first resilient pressing force with respect to the glass plate to form the first cut line on the glass plate by said cutter blade, and a second step of pressing the glass plate by said cutter blade with a second resilient pressing force with respect to the glass plate to form the second cut line successively connected in series to the first cut line on the glass plate by said cutter blade, an intensity of the second resilient pressing force being different from that of said first resilient pressing force, to thereby form on the glass plate the cut line including the first and second cut lines.
A glass plate cutting machine comprising:
- a cutter blade for forming a cut line on the glass plate, said cut line including a first cut line on the glass plate and a second cut line successively connected in series to the first cut line on the glass plate;
- moving means for moving said cutter blade along the cut line which has been preset and is to be formed on the glass plate;
- a resilient pressing device for resiliently pressing said cutter blade against the glass plate;
- and a control unit for controlling said resilient pressing device so as to change over a resilient pressing force of said cutter blade with respect to the glass plate in the movement of said cutter blade by said moving means,
- said resilient pressing device including a first resilient pressing force generating device for imparting a first resilient pressing force to said cutter blade, and a second resilient pressing force generating device for imparting a second resilient pressing force, an intensity of which is different from that of the first resilient pressing force, to said cutter blade, and
- said control unit is adapted to control the first and second resilient pressing force generating devices so as to form the cut line on the glass plate in the movement of said cutter blade by effecting for several times a cut line forming step of forming the cut line on the glass plate in the movement of said cutter blade, said cut line forming step having a first step of pressing the glass plate by said cutter blade with a first resilient pressing force with respect to the glass plate to form the first cut line on the glass plate by said cutter blade, and a second step of pressing the glass plate by said cutter blade with a second resilient pressing force with respect to the glass plate to form the second cut line successively connected in series to the first cut line on the glass plate by said cutter blade, an intensity of the second resilient pressing force being different from that of said first resilient pressing force, to thereby form on the glass plate the cut line including the first and second cut lines.
