A5SC Flat Wire Belt: The A5SC belt was specifically designed for the can industry by Ashworth Bros., Inc. Its special construction allows it to run under inverted cans, without pinching and upsetting them, which can occur at the discharge of the dryer section in a can washer, where the cans transfer onto the take-away conveyor.
Auxiliary Drive: The sprocket drive that sets the belt speed. This normally is located at the discharge of a spiral conveyor just before the take-up. See also take-up and tension drive.
Balanced Weave: A woven fabric consisting of alternating right and left hand spirals joined by crimped connecting rods to form a continuous belt. In some fabrics straight connecting rods are used.
Bar Capping: Wear strips, typically UHMW, installed on the cage bars.
Bar Links: Links typically used on Omniflex, Mega-Flex and Hybriflex belts that determine the strength of the belt. The bar links are assembled in a "shingled" configuration to allow the links to nest as the inside belt edge collapses in a turn.
Belt: The completed product consisting of a skeleton with or without mesh and attachments suitable for flexing around pulleys or sprockets and used primarily as a means of conveyance.
Belt Supports: Structure that the belt rides on (also called supports). Typical belt supports are UHMW and metal rails which can be arranged in a herring bone pattern or arranged horizontally in the direction of belt travel.
Belt Trackers (Control Rolls): Devices called control rolls are used to guide the belt's path. Control rolls are placed 1.5 x BW from terminals.
Black Specs: Dark colored wear debris from the system, product or belt that contaminates the product or product appearance.
Brazed Edge or Soldered Edge: An edge finish completed by brazing or soldering only.
Burrs: Metal protrusions on metal parts due to dull tooling, improperly punched or cut parts of the belt.
Cage: Large cylindrical shaped core of a spiral system. The system's main driving component. Also see Drum.
Cage Bars: The vertical members that form the driving surface of the cage or drum in a lotension spiral system.
Cantilever: Horizontal structural member with one end attached to the support columns and the other end free, that the belt supports are mounted on.
Center Link Position: Distance between inside edge of belt and centerline of center link in small radius belts.
Chain Driven Belts: A belt construction which provides positive traction by incorporating two or more rows of chain attached to cross rods or flatbar. Chains commonly used for this purpose are attachments, pintle and roller, which are connected by means of cross members.
Christmas Tree: Condition caused by over tensioning of the turn curve belts, typically in spiral systems, in which one edge of the belt bows in the direction of, or opposite of belt travel.
Cleatrac Belting (CTB): Precision balanced weave wire mesh fabric consisting of alternating right and left-hand spirals joined by crimped connecting rods.
Column: The structural member that forms the main support for the entire spiral system and is located circumferentially around the system.
Compound Balanced Weave: A fabric consisting of alternating right and left hand spirals nested together, and joined by three or more crimped connecting rods. In some fabrics straight connecting rods are used.
Compressed Spiral Edges: An edge finish in which the outer turns of the spirals are compressed to a specified distance.
Connector Rod: A wire or rod of any shape (usually round) either straight or crimped, used for joining belt components.
Conventional Weave: A fabric consisting of a series of either all right or all left hand spirals each turned into the preceding spiral to form a continuous belt. (For basic types, see one directional and sectional weave.)
Crimped Connectors: Round wire formed into peaks and valleys to house spirals. This crimp design pre-seats and stabilizes spirals, which reduces break-in stretch and prevents lateral spiral movement.
Cross Over: Length of straight running belt between centers of two cages on a two cage one belt system.
Dancer Roll: Weighted roll at the bottom of a take-up loop.
Dirty Systems: Process dirt and belt wear debris may contaminate product, increase system friction and accelerate belt wear, thus reducing the useful life of the belt if the user does not practice proper cleaning. Cleaning practices and schedules are application specific.
Dividers: Devices used to separate a belt into longitudinal product lanes. These can be created with woven wire designs or plate attachments.
Double Balanced Weave: A fabric consisting of pairs of interlaced right and left-hand spirals joined by crimped or straight rod connectors in a manner so that the pairs of spirals are inter-spaced by the adjacent spirals.
Double Rod Reinforced Weave (Dual or Duplex Weave): A fabric consisting of pairs of either all right hand or left hand spirals, each pair being turned into the preceding pair, and reinforced with a rod through the hinging point of the spirals.
Double Weave (Duplex) Edges: Edge construction of double weave design extending in from both edges to a specific distance.
Down Cage: A spiral system where the belt's travel is from top to bottom.
Drum: Large cylindrical shaped core of a spiral system. The system's main driving component. (Also see Cage.)
Drum Diameter: Diameter of the drum or cage.
