Rubber belts - Import export

Keiper CROMA high-performance flat belts are made of fully synthetic polyamide foils, with a one-sided or two-sided adhesion coating of chrome-split leather. Fitted with a polyamide reinforcement. With a one-sided or two-sided coating of chrome-split leather, highly resistant to abrasion and wear. Chrome-split leather is used exclusively as a friction coating on power transmission belts as an alternative to nitrile-butadiene rubber (NBR). CROMA belts with a coating of chrome-split leather are perfect for power transmission applications where the rollers are considerably contaminated by oil and dirt. In view of its slightly porous surface, chrome-split leather is air and humidity permeable and absorbs moisture; thus, it retains friction. However, the coefficient of friction of leather is lower than that for nitrile-butadiene rubber and steadily decreases during operation.

KEIPER has an extensive range of flat belts, including high-performance flat belts, power transmission belts, folder-gluer belts, machine belts, tangential belts and conveying belts. For the perfect power transmission, conveying or control solution in any industrial sector. Keiper flat belts are designed to meet your specific requirements and applications, and, accordingly, they are made to size. Our flat belts are made of different traction layers and composite structures with different coatings such as nitrile-butadiene rubber, leather and surface structures.

Finishing on a sanfor line provides the fabric with a more stable structure, a silklike shine, a smoother touch and minimum residual shrinkage. The rubberbelt compacting line is made for the sanforisation and compacting of woven fabric and some kinds of knitted fabric, in combination with a felt belt calender the fabric gets on these lines additionally a special touch. The benefits are among others optimum residual shrinkage due to the hightech drive concept, stabilisation of the fabric structure, silklike shine, soft fabric touch, absolutely constant shrinkage due to a new automatic shrinkage control system available as option, production speeds up to 100 m/min are possible, extended service life of the rubber belt due to the larger diameter of the compacting rollers and an optimised rubber belt cooling system, integrated menudriven rubber belt grinding process, minimisation of vibrations, all bearings arranged outside of the wet area and therefore no corrosion.

Compacting is the last finishing process after relaxation or drying and has thus decisive importance for the residual shrinking, the hand and the aspect and the shine of the fabric before cutting and makeup. The BRÜCKNER compacting calender is characterized by an extremely short fabric path, an optimum traction control and a sophisticated drive technology allowing high production speeds with consistent fabric quality. Depending on the fabric type and the quality requirements, BRÜCKNER can offer the following compacting solutions two felt belt compactors arranged one behind the other, rubber belt shrinking unit according to the Sanfor principle, rubber belt shrinking unit with downstream arranged felt belt compacting calender. In addition, the following units can be integrated into the compacting line equalizing frame for the overspreading and width control, straightener, steamer unit, edge cutter (knife or scissor type).
