Product Overview

The KR‑503 Bally leather flexometer is benchtop laboratory equipment for evaluating cyclic flex‑crack resistance of thin flexible materials including genuine leather, coated fabrics and shoe‑upper textiles. Following BS‑3144 and JIS‑K6545 testing methodology, prepared specimens are securely clamped on both inner and outer edges. The mechanism drives repeated reciprocal 22.5‑degree reverse folding motion. After completing predefined flex cycles, technicians examine test pieces for crease cracking, surface flaking and fibre rupture to judge material anti‑flex‑fatigue performance.

Two configurable variants are available: 6‑station and high‑throughput 12‑station models. This instrument is widely adopted in tanneries, footwear‑manufacturing plants, luggage‑goods factories, material‑R‑D labs and accredited third‑party inspection bodies for incoming‑material QC and new‑formula performance comparison for shoe uppers, apparel leather and bag‑making materials.

Core Product Competitive Advantages

1. Two‑model flexible station‑count selection 6‑station variant fits routine small‑batch evaluation with compact footprint; 12‑station high‑capacity version supports multi‑sample parallel testing for heavy‑volume laboratory workloads, greatly boosting daily inspection throughput.
2. Standard‑compliant stable folding kinematics Maintains 22.5° reverse‑bending angle. Precision crank‑linkage transmission delivers uniform reciprocal folding movement, reproducing repeated creasing stress leather receives in real‑life service and lowering mechanical‑caused test deviation.
3. High‑capacity LCD preset counter with auto‑halt Wide‑range 0‑999 999 cycle setting. Unit automatically stops once target flex repetitions are reached. Eliminates manual stop‑watch counting mistakes for regular quality‑control workflows.
4. Durable quick‑clamp specimen‑fixture assemblies Stainless‑steel clamping jaws hold 70 × 45 mm standard‑size samples firmly without slippage during long‑time cyclic flexing. Quick‑release knob‑type clamps simplify specimen replacement between test batches.
5. Solid anti‑vibration desktop cabinet design Heavy‑duty metal base with anti‑slip levelling feet suppresses operating vibration. Front‑panel keypad‑and‑display layout delivers straightforward operation, lowering skill‑threshold for workshop‑QC operators.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place tester on level firm lab‑bench, adjust anti‑vibration feet. Inspect crank‑linkage transmission and clamping‑jaw condition. Cut leather / textile specimens into standard 70 × 45 mm size. Power‑on unit and run short idle‑stroke check.
2. Specimen Mounting Open quick‑release clamps. Fix each test‑specimen securely by both inner‑edge and outer‑edge. Ensure sample lies flat without distortion before tightening clamping knobs.
3. Parameter Configuration Set target total flex‑cycle number on LCD control panel. Double‑check folding‑angle mechanical‑position conforms to 22.5‑degree standard requirement.
4. Execute Bally Cyclic Flex‑Resistance Test Press start‑button. Machine carries out continuous reciprocal reverse‑folding cycles. Equipment automatically halts upon reaching preset cycle value.
5. Result Observation & Record Take‑out specimens. Carefully inspect folding crease zone for cracking, coating‑peeling or fibre‑breakage. Document damage degree for QC‑report. Multiple replicate‑specimen tests are recommended for statistically‑valid evaluation conclusion.
6. Post‑Test Tidying Remove tested samples. Clear fibre debris from clamping‑jaws. Reset counter‑parameters for next‑batch‑testing. Periodically check linkage‑lubrication and fixture‑fastening‑bolt tightness.

Safety‑Operation‑Reminder

Keep hands away from moving folding‑fixture range during equipment‑running. Confirm specimens are fully clamped before starting test‑cycle. Reliable equipment‑grounding must be completed before power‑on. Periodically inspect transmission‑linkage and fixture‑fastening‑condition.
