SPECIFICATION
- Bally flexometer is designed to test flexing resistance by flexometer (Bally) sole, leather and leather products, coated fabrics and textiles used in footwear upper.
- It is internationally accepted method for the assessment of the flexing endurance of light leathers and their surface finishes.
- The tendency for cracks to form in the creases caused by walking can also be determined.
- The machine has at least six stations and leather upper clamp consisting of a pivoting pair of flat plates of maximum 4m thickness.
- One plate has the basic shape of a trapezium ABCFD, but with a radius of 2mm at F.
- It has a ledge EF 4mm±1mm thick to support the folded test piece. The other plate has the shape EGHCF. clamp tightening screw draws the plates together and also acts as a stop to prevent the test piece from being positioned closer to AB than the vertical through C.
- A stop near the edge AB and approximately midway between A and B ensures that the plates clamp more effectively near point F. The upper clamp reciprocated by a motor about a horizontal axle, descending through an angle of 22º30’±0o 30’ at a frequency of 100 cycles/min ± 5 cycles/min.
- The lower clamp, fixed and lying directly beneath (planar to) the upper clamp and consisting of a pair of flat plates to hold the test piece. Position of the lower clamp distance between the ledge EF and the upper edge of the fixed lower clamp, when the ledge EF is horizontal it is 25.0mm±1.0mm. There is a counter to indicate the number of cycles. A pre-determined counter. Test position: 6 sets, Type of upper gripe: A or B type gripe, flexing angle: 22.5° ± 0.5°, Flexing speed: 100 ± 5 cycles / flexes per minutes, Counter: 0 to 999999 (adjustable), Sample size: 70 ± 5 X 45 ± 5 mm, Dimension (L x W x H) mm: (950 x 600 x 500) mm, Weight: 60 to 85kgs.
