How ALLIGATORŽ Staple Fasteners Work

Designed for today's light and middle synthetic carcass belting, the ALLIGATOR fastener utilizes high tensile, stainless steel staple attachment, in conjunction with an extended plate design. This design separates the point of fastener penetration from the line of belt flexing to eliminate splice fatiguing (sawing) action at the point of attachment.

Staple fasteners are furnished in strips with a bridge between each fastener plate. This strip design prevents individual parts (as with belt hooks or teeth in other styles of fasteners) from getting into the product being conveyed. It also provides a stronger splice, greater resistance to impact damage and a smoother, unrippled joint that helps make hinge pin insertion easier.

Staples are hammer driven through the fastener and belt, working between the carcass fibres without severing them. The staples are then clinched cross-wise to the belt; in this way, belt tension does not pull against the staples to unclinch them.

Applications
Light and medium-duty conveyor belts in package and baggage handling, cased goods, parts, food, wood and agricultural products.

Installation Method
A portable, lightweight application tool is easily carried to the job for on-site installation. Holds belt and fastener while staples are driven with a hammer.

Fastener Profile
Fastener has a smooth, low profile for operating with diverters and shears.

PIW (pounds per Inch width)
For belts with mechanical fastener ratings up to 250 PIW or 44 kN/m.

Pulley Diameter
ALLIGATOR Staple fasteners operate smoothly over pulleys as small as 2" or 50mm In diameter (No. 62).

Splicing Method
One-piece fastener strips are attached to the belt with stainless steel staples. Staples are driven through the plates and clinched cross-wise on the belt to resist opening up after being set.

ALLIGATOR Ž Lacing fasteners come in 300mm lengths depending on size.

How ALLIGATOR Lacing Works

ALLIGATOR Lacing utilizes a design with teeth that enter parallel to the length of the belt and imbed clear through the belt carcass. The teeth are formed so that when they are driven into the belt, the vital longitudinal carcass fibres are not severed.

Additional strength is obtained due to the connecting bar and because the fastener strip is one continuous piece, this provides a strong, vice-like hold on the belt and distributes belt tension evenly across the entire belt width. The one-piece fastener strip also insures that there are no loose pieces to work themselves out of the belt and into the conveyed product. The straight splice obtained with a continuous strip of lacing also helps with hinge pin insertion.

Applications
Manufacturing assembly lines, food, package and parts handling, checkout counters and agricultural equipment.

Installation Method
Requires only a hammer, no special tools needed. Unique, patented clips and round gauge rod act as an "extra pair of hands" for production splicing, ALLIGATOR belt facing machines are offered.

Fastener Profile

Low profile, one-piece design results in an exceptionally smooth joint.

P.I.W (pounds per inch width)
Use with belts that are mechanically rated up to 200 PIW or 35 kN/m (maximum recommended tension range varies by lacing size).

Pulley Diameter Range
ALLIGATOR Lacing operates over a wide range of minimum pulley diameters from 1" or 25mm to 13.5" or 350mm, depending on lacing size.

Splicing Method
ALLIGATOR Lacing is a continuous one-piece fastener strip, tailored to all standard belt widths. Lacing is secured with teeth that imbed lengthwise on the belt, providing a strong, vice-like attachment.
