Drawdown belts are used in the packaging industry when something is filled into a folia or paper bag. Drawdown belt is also called haul off or bagger belt , coated belt, vacuum belt, or VFFS belt . The later term is an abbreviation from Vertical Fill Form and Seal Machine, one type of packaging machine where the draw-down belt hauls off the folia to form a bag. The drawn-down belt consists of a basic toothed belt and a cover. The basic belt is around 90 ShA while the cover should be much softer ranging from 35-55 ShA to sti SPECIAL BELTS FOR PACKAGING INDUSTRY ck to the folia or paper they draw for packaging the product into a bag. For the basic belt manufacturers can use either Polyurethane (PU) or Neoprene timing belt. A lifetime of PU is longer. If you prefer a longer life you should buy PU basic while if the price is a preference you should buy Neoprene. However, if you consider stopovers/ change periods and maintenance cost no question PU is more economic. Neoprene basi


1 – Material:  What is in contact with the Roller?  Metal  Plastic  Wood  Urethane  Natural rubber  Corrugated cardboard  Other material 2 – Product weight:  What will be the maximum weight? 3- Desired transportation speed:  How fast do you want to move the article? Feet/minute (FPM) Meters/minute (MPM) 4 – Diameter of the roller:  What diameter are you looking for? Common Roller Diameters 1.50” (38.0mm) 1.68” (42.7mm) 1.91” (48.6mm) 2.25” (57.0mm) 2.38” (60.5mm) 2.50” (63.5mm) 3.00” (76.3mm) (Convert English units to Metric units, 1 inch=25.4 mm) 5 - Between frame dimension:  What is your between frame dimension (BF)? In determining the correct length of the ROLLERS required, you should first obtain the between the frame width of the conveyor you will be mounting the in. All dimensions need to be converted to millimeters. Take the between the frame width and subtract 15mm to account for bearing end caps and clearances to


There are several ways that a timing belt can be identified. Many times the timing belt part number and the name of the timing belt manufacturer will be printed on the timing belt and will still be legible. While this is the ideal situation, there are many times when the timing belt part number is either incomplete, vague, or from a belt manufacturing company that is either out of business or has a timing belt numbering system that isn't easily cross referenced. If the timing belt isn't marked adequately, there are times when the timing pulleys are marked adequately to determine the pitch and profile of the timing belt. The pitch of the timing belt is the distance from the center of one tooth to the center of the next tooth. The problem is that there are several different tooth profiles or shapes for 3mm, 5mm, 8mm and 14mm pitches not easily discernible without proper tooling. These include the Conti AT5/T5, HTD/ STD, Power Grip HTD/ Power Grip GT2 and Poly Chain prof

V Belt Manual

1. Classical V Belts: . The first of the V belts to enter in  power transmission.  . Maximum permissible speed = 30m/s . In   application where reverse idlers are not used , classical V belts are more   advanta geous other       than because of smaller heights. 2. Wedge V  Belts:  . Wedge belts can transmit higher power 1.5-2 times than of classical belts with the same top width. . Maximum permissible belt speed = 42m/s . Wedge belt is primarily used in new drives to achieve space saving. . Extensive use in industrial application from light duty application to heavy duty application. 3. Narrow V Belts:  . Constructionally & properties wise Wedge V belts & Narrow V belts are same, the only difference additional ridge top provided in Narrow belts. . Maximum permissible speed = 42m/s 4. Hexagonal V Belts: . Hexagonal V belts are also called double V belts. . Hexagonal belts are used where several pulleys in the same plane driven clo

CXP Vs CXA Heavy Duty Drive Belt

Hello Everyone.....!!! Today we shall share the difference between Conti CXP & CXA Timing Belt. CXP & CXA Rubber Belt Properties: Oil resistant to a degree Tropics resistant UV and ozone Electrically conductive (Anti-static) to ISO9563 Temperatures ranging from -20°C to +100°C Increased power ratings CXP heavy-duty, high speed drive belt The CXP range has a specifically developed tension member and exceptional material bonding. The teeth and the belt top are made from a synthetic Rubber mix with high tear resistance and enhanced shear resistance, to ensure reliable sustained power transmission at belt speeds up to 50m/s. The CXP range is used where high power must be transmitted above 1000RPM. Glass Fibre Tension Member These tensile members have a high flexural fatigue strength along with a highly reliable power transmission capability up to 50m/s. CXA heavy-duty, low speed drive belt The CXA range combines exceptionally hig
