The brush bristle combing machine processes natural bristle materials before they are used in tufting. Natural bristles-from pigs, horses, and other animals-arrive in bundled form with varying lengths, uneven orientation, and mixed diameters. The combing machine aligns these bristles into orderly tufts, separates them by length, and removes broken or damaged filaments. This preparation step is essential for manufacturers using natural bristles, because the raw material is not uniform enough to feed directly into tufting equipment. The combing machine ensures that the tufting machine receives bristles of consistent length and orientation.
Why Natural Bristles Need Preparation
Unlike synthetic filaments produced in controlled manufacturing processes, natural bristles grow organically with individual variations. Within a single bundle, bristle length varies, the tips may curl, and the lower ends may be frayed or cross-sectionally varied. Feeding unprepared bristles into a tufting machine produces uneven tufts and inconsistent brush surfaces, because the random length and orientation cause some bristles to extend beyond the intended cut line. The machine addresses this by aligning the bristle tips and ensuring the lower ends are even. The combing process also separates usable bristles from those that are too short, broken, or damaged, reducing waste during tufting.
The machine uses needles or pins that pass through the bristle bundle to straighten and align individual filaments. The combing action removes shorter bristles from the top of the bundle while leaving the longer ones, gradually separating the material by length. The combing depth and speed are adjustable to match different bristle types and desired length grades. Pig bristle has a characteristic taper and curve, requiring slower combing speeds to avoid breaking. Horsehair is finer and requires gentler treatment to prevent damage. Shengfeng Machinery's team recommends combing parameters for each natural bristle type based on the company's processing experience.
Quality and Testing Standards
Each machine undergoes a trial run using natural bristle material before shipment. The trial confirms that the combing mechanism operates smoothly without damaging bristles, that the length separation meets requirements, and that the output material is ready for tufting. The machine's needles or pins are inspected and adjusted during the trial to ensure proper depth and spacing. Shengfeng Machinery offers sample testing services, allowing customers to send natural bristle samples for verification of combing quality before placing an order.
The brush bristle combing machine has a standard delivery time of 30 days. Custom combing configurations-such as specialized needle arrangements for particular bristle types-require up to 50 days. A 6-month warranty covers manufacturing defects, with free parts and remote support during the warranty period. Monthly production capacity is approximately 15 units. The minimum order quantity is one machine. Payment terms follow the 40% deposit and 60% balance structure for standard orders. The machine is packaged in ISPM-15 compliant wooden crates for export. Third-party inspections are accepted.
