Abstract
Abstract A strip load simulator for calibration of a shape-measuring roll with load sensing devices has an endless belt tensioned between two pulleys and mounted in a frame pivoted so that the belt rests on the roll surface. When the roll is rotated, the weight of the frame, belt and pulleys moves the belt and provides a reproducible force to calibrate the load sensing devices.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
77 words
A strip load simulator for calibration of a shape-measuring roll having load sensing devices comprising a frame, a pair of spaced apart pulleys mounted on said frame and having axes generally parallel to the axis of the measuring roll, a flat endless belt passing over said pulleys and means for tensioning said belt whereby when the measuring roll is rotated and said tensioned belt is forced against said Roll surface, the load sensing devices may be calibrated.
Claim 2
Dependent Claim
77 words
A strip load simulator for calibration of a shape-measuring roll having load sensing devices comprising a frame, a pair of spaced apart pulleys mounted on said frame and having axes generally parallel to the axis of the measuring roll, a flat endless belt passing over said pulleys and means for tensioning said belt whereby when the measuring roll is rotated and said tensioned belt is forced against said Roll surface, the load sensing devices may be calibrated.
Claim 3
Dependent Claim
79 words
A strip load simulator according to claim 1 in which said frame is located above said measuring roll and is pivotable at one end on an axis generally parallel to the axis of the measuring roll whereby the weight of said frame, pulleys and belt provides said force against said measuring roll and which includes means for moving said frame laterally along said pivot axis and means for holding said frame in a desired position along said pivot axis.
Claim 4
Dependent Claim
110 words
A strip load simulator according to claim 1 in which the means for tensioning said belt includes a fixed mounting block in said frame for mounting one of said pulleys, a pair of spaced apart guide rods connected to said fixed mounting block, a movable mounting block for mounting the other pulley and adapted to move along said guide rods, a threaded member attached to each guide rod between said mounting blocks, an adjustment nut engaging each threaded member, and a compression spring between said adjustment nut and said movable block whereby said adjustment nuts may be rotated to compress said springs against the movable block thereby tensioning said belt.
Claim 5
Dependent Claim
79 words
A strip load simulator according to claim 3 in which said frame is located above said measuring roll and is pivotable at one end on an axis generally parallel to the axis of the measuring roll whereby the weight of said frame, pulleys and belt provides said force against said measuring roll and which includes means for moving said frame laterally along said pivot axis and means for holding said frame in a desired position along said pivot axis.
Claim 6
Dependent Claim
22 words
A strip load simulator according to claim 4 in which said belt is a poly-V-groove belt and said pulleys have matching grooves.
