Abstract
A method of and apparatus for scoring block size glass sheets into shapes for further fabricating into automotive windshields, side lights and the like. The apparatus includes a continuously operating conveyor for advancing the block size glass sheets to and from a scoring station, including a sheet capturing mechanism whereat a sheet is captured and held in a predetermined position on an operating roll conveyor beneath a positionable scoring unit which produces at least one score line on the glass sheet along a predetermined path. Thus the scored sheet, when released, is quickly conveyed away from the scoring station.
Claims11
A method of scoring glass sheets comprising the steps of:
- a. advancing a glass sheet on a continuously running conveyor along a rectilinear path through a scoring station;
- b. capturing the glass sheet at the scoring station and holding the sheet stationary on the running conveyor;
- c. selecting at least one path along which the captured sheet is to be scored at an angle other than 90.degree. relative to said rectilinear path;
- d. scoring the upper surface of said captured sheet along said at least one path;
- and
- e. releasing the scored glass sheet whereupon the sheet is quickly conveyed away from the scoring station.
An apparatus for scoring glass sheets, the apparatus comprising:
- a. a scoring station;
- b. a continuously operating means for conveying the glass sheets along a rectilinear path beneath said scoring station and for supporting the glass sheet at said scoring station;
- c. means for capturing and holding the glass sheet in a stationary position at the scoring station during scoring of the glass sheet;
- d. at least one guide rail extending along the rectilinear path at an angle other than 90.degree. relative thereto, and bridged over the glass sheets above said predetermined location;
- e. means for positionably suspending said guide rail above said conveying means above said predetermined location of the glass sheet;
- and
- f. a scoring tool movable along said guide rail for scoring the captured glass sheet along a predetermined path.
