The minimum tension in any portion of the carrying run of a belt necessary to prevent excessive sag of the belt between idlers.
A piece of material removed for evaluation.
A device for cleaning the surface of belting.
The place where two edges of fabric or elastomer are adjacent to each other to form a single ply or layer.
Seaming strip
A strip of polymeric material laid over and/or in a seam to fill any voids between the adjacent plies of material.
Self-aligning idler
An idler having a belt-activated swivel mechanism to control the side movement of an operating conveyor belt.
The lengthwise woven edge of a fabric. Also called selvedge.
A partial or incomplete cure.
Service condition
All the conditions of operation to which a conveyor or elevator belt is exposed.
Service factor
The amount by which the normal rating of a unit is altered to compensate for specific service requirements.
Service test
A test in which the product is made to operate under service conditions in the actual equipment.
The amount of deformation remaining after complete release of the load producing the deformation.
A bas-relief or outline of a reinforcement which appears on a cover after vulcanization.
A form of plastic in which the thickness is very small in proportion to length and width and in which the plastic is present as a continuous phase throughout.
Shelf storage life
The period of time prior to use during which a product retains its intended performance capability.
Simulated service test
See bench test.
Singles yarn
The product from aligning and twisting together fibers or twisting together filament fibers.
A collapsed blister or bubble leaving a depression in a product.
Amount by which the ends of a single pick yarn in a fabric are offset longitudinally.
A thin layer of polymeric compound applied to a fabric.
Skim or skim coat
A layer of rubber material laid on a fabric but not forced into the weave. Normally laid on a frictioned fabric.
Skirt board
In a conveyor system, the vertical or inclined plates located longitudinally and closely above the belt to confine the conveyed material.
A cut or grinding action made on an angle to the surface to produce a tapered or feathered end.
Slab belting
Belting made in wide widths and long lengths for later slitting into narrower widths and cutting into shorter lengths.
Slack side tension
The lessor of the tensions in a belt on an operating conveyor. Usually immediately following the drive pulley.
Slider bed
A stationary surface on which a belt slides.
Slider bed conveyor
A conveyor belt operating all, or in part of its length, over a flat support surface as opposed to being supported by a series of rollers.
The action that takes place, causing a differential movement between the pulley surface and the belt.
Slip and sequence system
An interlocking belt conveyor system that stops the system when the speed of the conveyor belt drive pulley exceeds a certain speed of the conveyor belt.
Slit belt
A belt cut to lesser width.
Slit edge
The square finished edge of a belt after trimming to width.
Slit edge belt
See cut edge.
Slope belt
A conveyor belt used to carry material along an inclined flight.
Slope tension
See tension, slope.
Snub pulley
A pulley adjacent to a drive pulley that increases the arc of contact on the drive pulley to increase the effectiveness of the drive.
Solid woven belt
A type of conveyor belt wherein the carcass is a single ply consisting of multiple layers of warp and filling yarns interwoven. The carcass usually is impregnated and/or coated with polymeric compound.
Detail description of specific requirements.
A piece cut from a sample of belting to test.
Methods for joining the ends of belting together without using a mechanical fastener.
Splice angle
The angle at which belting is spliced.
To apply a thin coat of liquid material over a surface by means of a knife, bar, or doctor blade.
Spread coat
To apply a thin coat of material over a surface determined by means of a knife, bar, or doctor blade.
Spread coated fabric
A fabric coated with a liquid plastic by a spreading process and then heated to fuse the coating.
Spring take-up
A mechanical device on both sides of the conveyor system where a variable force spring is secured to the conveyor structure and to the tail pulley block for the purpose of maintaining a uniform tension in the belt.
Spun yarn
A yarn produced from short fibers by aligning and twisting them together.
Square edge
An edge of plastic-covered belting finished against rectangular irons.
A conveyor adapted to piling or stacking bulk material, packages, or objects.
Stamped metal
Perforated metal sheet used for making a rough top design on a conveyor belt.
A quality level set for the results from a belt test.
A textile fiber of relatively short (1″ to 3″) length which when spun and twisted forms a yarn.
Staple fiber
The short fibers from which a spun yarn is made.
Starting tension
The tension necessary to accelerate a belt from rest to normal operating speed.
Static conductive
Capability to conduct static electricity.
Static electricity
Electrical potential resulting from two surfaces rubbing together or parting one from the other.
Static friction
The resistance which must be overcome to start a body sliding down a belt surface.
Steel cable
Several steel cords twisted together.
Steel cord
Several steel wires twisted together.
Steel cord belt
A conveyor belt having a tension bearing member of steel cords lying in the same plane with a definite spacing between the cords, elastomer between the cords and an elastomeric cover on both sides of the belt.
Step ply
A conveyor belt having a plied textile carcass in which the upper ply or plies are set back toward the edges to increase the cover gauge in loading area.
Stepped splice
The joint of one end of multi-ply belting with plies of fabric removed so respective ply ends will butt together and overlap adjacent plies of fabric.
Resistance to flexing.
A method of butting or joining two pieces of material together, usually by means of a stitcher roller.
Stock roll
A belt made to some nominal length and width for subsequent cutting to required length and width.
Straight face pulley
A pulley without any crown.
Straight warp weave
Two warp yarn systems and a filling yarn system where one warp system is essentially without crimp and is the tension bearing member, while the other warp system is interlaced with the filling yarn and provides mechanical fastener holding capability.
Deformation resulting from a force applied to a body.
Force applied to a body that results in the body being deformed.
