Full definition
A method of joining conveyor belt ends using chemical adhesives and self-vulcanizing rubber cement at ambient temperature, without a vulcanizing press. The belt ends are prepared by stripping back the cover rubber, stepping the plies at calculated lengths (finger splice pattern for multi-ply belts), applying primer and two-component cement (e.g., Rema Tip Top SC 4000 with hardener E-40), laying in splice rubber, and pressing with a hand roller/stitcher. Cure time: 4-12 hours at 20°C (longer in cold conditions, shorter in warm). Achieves 60-80% of original belt strength — intermediate between mechanical (50-70%) and hot vulcanized (90-100%). Advantages: no press needed (field-portable), lower equipment cost, suitable for remote locations. Disadvantages: longer downtime waiting for cure, sensitive to temperature and humidity, requires skilled technician. Per splice manufacturers specifications (Rema Tip Top, Almex, Beltwin). Splice life: 50-80% of hot vulcanized splice life. Best for medium-duty belts up to EP800/4.
