TAIL END: Usually the end of a conveyor nearest loading point.

TAIL PULLEY: A pulley mounted at the tail end of a conveyor, its purpose is to return the belt.

TAKE-UP: The assembly of the necessary structural and mechanical parts which provide the means to adjust the length of belt and chain to compensate for stretch, shrinkage or wear and to maintain proper tension.

TANGENT: Straight portion after a curve conveyor.

TAPERED ROLLER: A conical conveyor roller for use in a curve with end and intermediate diameter proportional to their distance from center of curve.

TAPERED ROLLER CURVE: A curved section of roller conveyor having tapered rollers.

THROUGHPUT: The quantity or amount of product moved on a conveyor at a given time.

TOTAL LOAD: Amount of weight distributed over the entire length of a conveyor.

TRACKING: Steering the belt to hold or maintain a desired path.

TRAFFIC COP: A mechanical or electrical mechanism to prevent collision of objects as they merge from two conveyor lines into a single line.

TRANSFER: A device or series of devices, usually mounted inside a conveyor section, which uses belts, chains, 0-rings, rollers, or skate-wheels, to move products at right angles to adjacent or parallel conveyor lines.

TRASH CONVEYOR: A conveyor, normally a belt conveyor equipped with high side guards, used in transporting empty cardboard boxes and paper trash away from working areas. (TH)

TREAD PLATES: Diamond top steel filler plates used to till gap between rollers on roller conveyor.

TRIPOD SUPPORT: Three legged stand for small roller and skatewheel conveyor. Usually easily moved or aligned to maintain elevation of the conveyor.

TROUGHED BED: A conveyor designed with a deep trough used for carrying broken glass, cans, wood chips, stampings, etc. Also used in recycling operations. (TR, CRB)

TROUGHING ATTACHMENTS: Angles used on belt conveyors to cup the edge of the belt.

TURNBUCKLE: A link with a screw thread at both ends, used for tightening the rod, normally used in cross bracing.

TURNING WHEEL: Wheel mounted on an adjustable bracket to help insure proper package orientation.

TURNTABLE: A horizontal, rotatable conveyor mechanism used for transferring objects between conveyors that are in angular relation to one another. (900, 1800, 360E)

TWO-PULLEY HITCH: A special transition section for moving product from horizontal to incline. (TH)

UNDERSIDE BED COVER: Sheet metal used to cover the underneath side of a conveyor.

UNDERSIDE TAKE-UP: A take-up section located beneath the bed of a belt conveyor.

UNDERTRUSSING: Members forming a rigid framework underneath the conveyor, used for supporting the conveyor.

VARIABLE SPEED: A drive or power transmission mechanism that includes a speed changing device. Standard mechanical variable speed ratios 6:1 A.C.; electrical variable speed ratio 10:1.

V-BELT: A belt with a trapezoidal cross section for operation in grooved sheaves permitting wedging contact between the belt sides and groove sides.

ZERO PRESSURE ACCUMULATING CONVEYOR: A type of conveyor designed to have zero build-up of pressure between adjacent packages or cartons. (SPEZ, ABEZ, LREZ, CREZ, CCEZ, CCAC, DCEZ, PREZ)
