Abstract
Abstract A process for rolling profiled glass bars and an apparatus for this purpose whereby a horizontal roller arrangement with at least one cylindrical roll surface and a pair of lateral roller arrangements, each with a respective roll surface contact the glass ribbon to deform the latter into the desire profile. Means is provided for driving the outer roll arrangements at 0.5 to 1.5 percent higher peripheral speeds than the central roll arrangement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
82 words
A process for the continuous production of a profiled glass bar, comprising the steps of feeding a plastically deformable glass ribbon along a transport path, engaging a central portion of said ribbon with a central roll surface having a horizontal generatrix and a horizontal axis, and lateral portions of said ribbon with outer roll surfaces having generatrices lying at an angle to the horizontal, and driving said outer roll surfaces at a higher surface speed than that of said central roll surface.
Claim 2
Dependent Claim
82 words
A process for the continuous production of a profiled glass bar, comprising the steps of feeding a plastically deformable glass ribbon along a transport path, engaging a central portion of said ribbon with a central roll surface having a horizontal generatrix and a horizontal axis, and lateral portions of said ribbon with outer roll surfaces having generatrices lying at an angle to the horizontal, and driving said outer roll surfaces at a higher surface speed than that of said central roll surface.
Claim 3
Dependent Claim
59 words
The process defined in claim 1, further comprising the step of engaging said ribbon with a pair of intermediate roll surfaces having substantially horizontal generatrices and flanking said central roll surface inwardly of said outer roll surfaces and driving said intermediate roll surfaces with a surface speed intermediate that of said outer roll surfaces and said central roll surfaces.
Claim 4
Dependent Claim
23 words
The process defined in claim 2 wherein said intermediate roll surfaces and said central roll surface are coaxial and of substantially equal diameters.
Claim 5
Dependent Claim
29 words
The process defined in claim 2 wherein the generatrices of said outer roll surfaces lying in a vertical plane are inclined at angles of about 45* to the horizontal.
Claim 6
Dependent Claim
30 words
The process defined in claim 2 wherein the surface speeds of said outer roll surfaces is 0.5 to 1.5 percent greater than the surface speed of said central roll surface.
Claim 7
Independent Claim
123 words
An apparatus for the production of profiled glass bars comprising a central roller arrangement having a central generally cylindrical roller rotatable about a generally horizontal axis and having a substantially horizontal generatrix while being engageable with a central portion of a glass ribbon; a shaft coaxial with and drivingly connected to said central roller; a pair of lateral rollers coaxial with and flanking said central roller and having generatrices inclined to said horizontal generatrix while being engageable with portions of said ribbon outwardly outside said central portion; and gear means connecting said outer rollers with said shaft and dimensioned to drive said outer rollers at a surface speed which is 0.5 to 1.5 percent greater than the surface speed of said central roller.
Claim 8
Independent Claim
123 words
An apparatus for the production of profiled glass bars comprising a central roller arrangement having a central generally cylindrical roller rotatable about a generally horizontal axis and having a substantially horizontal generatrix while being engageable with a central portion of a glass ribbon; a shaft coaxial with and drivingly connected to said central roller; a pair of lateral rollers coaxial with and flanking said central roller and having generatrices inclined to said horizontal generatrix while being engageable with portions of said ribbon outwardly outside said central portion; and gear means connecting said outer rollers with said shaft and dimensioned to drive said outer rollers at a surface speed which is 0.5 to 1.5 percent greater than the surface speed of said central roller.
