Description
On a vertical form-fill-seal machine the belt does not only transmit motion. It decides where the film stops, so it decides where the seal lands and how much film ends up as scrap. We build this belt as one seamless vulcanized loop with a controlled 3.00 mm target thickness, then slit, cover and machine it to your drawing. No splice, no weak point, no thickness step to upset registration. Most buyers compare belts by price per piece. Packaging lines pay for belts in a different currency: downtime, scrap, and operator time spent re-adjusting. These are the four failures we are asked to fix most often. Film draw-down loses registration, the seal lands off-centre and the jaw crushes product instead of sealing it. A spliced belt opens at the joint, delaminates under tension and fails long before the rubber itself is worn. Width or pitch tolerance off by a fraction is enough to make the belt track off the pulley and wear the flange. Premature wear forces an extra changeover. One hour of lost line output usually costs more than the whole belt order. Six properties that decide whether a belt holds registration on a vertical packaging line, or slowly drifts until the operator re-adjusts it every shift. The loop is formed in the mould. There is no joint to open up under tension, which is where most endless belts fail first. Target 3.00 mm with controlled deviation, so the belt seats evenly and transmission stays consistent from start to stop. Compound, colour and hardness selected for grip and product release, not pulled off a standard shelf. Cord selected for your load and elongation requirement, so the belt does not creep out of registration over time. Clean holes and smooth edges for consistent mounting, instead of uneven holes that tear at the fasteners. Compliance documentation supplied with the order for your incoming quality records. The joint is where a conventional endless belt fails first. We build the loop in the mould instead of closing it afterwards, so there is nothing to open up. Send a sample, a drawing or the pulley data. We confirm the matching structure, compound and tolerances before production, so the belt you receive fits on the first try. The complete set of our vulcanized timing belt product photos, in order: collection overview, structure details, customization options and specifications. Typical stations on vertical packaging and bagging equipment where a seamless endless belt is specified. Pulls the film down over the forming tube; the belt determines bag length accuracy. Synchronises jaw movement so the cross seal lands square on the bag. Small-format packaging where registration tolerance is measured in fractions of a millimetre. Continuous vertical bagging for snacks, granules and powders. Carries product from the multihead weigher into the forming tube without spillage. Holds the pack steady while the coder or labeller applies the mark. Standardized workshop and modern vulcanizing equipment under one roof. Long-term focus on industrial belt selection, matching and supply. Europe, the Americas, the Middle East and Asia, with repeat OEM programmes. Independent development of compounds, structures and core technology. Full-process quality control before anything leaves the plant. Utility model patents and compliance documentation available with your order. Yes. Send the sample, a drawing or the pulley data. We confirm the structure, compound and tolerances before production so the replacement fits on the first try. Our standard target is 3.00 mm. Other thicknesses are made to your drawing or sample. Yes. Width is slit to drawing or sample, and endless length is calculated from your drawing or the pulley centre distance. Yes. The loop is vulcanized endless in the mould, so there is no mechanical splice and no joint to crack or delaminate. Technical enquiries are answered within 24 hours, including a recommendation on structure and compound for your application. Tell us the machine, the pitch and the running conditions. We will tell you which structure and compound actually fits, instead of shipping a standard belt and hoping it works.A Vulcanized Timing Belt Built for VFFS Film Draw-Down
