SpanTech’s WG-MIN MiniLink WedgeConveyor, with its 2.36” [60mm] wide, 0.4”[10mm] Brush-Top Polyurethane chain, is idealfor small products. The MiniLink Wedge canaccommodate a range of lightweight products,from 1” [25.4mm] to 10” [254mm] in height.Product width is adjustable from zero to 12”[305mm]. The conveyor uses an all stainlesssteel “I-Beam” frame, eliminating plastic wearstrips and providing a cleaner, washdown-tolerant design. Support structures of powder-coated steel or stainless steel are available.
The MiniLink Wedge Conveyor is offered in astandard “positionable” version and anoptional, fully adjustable version. Thepositionable unit is designed to be set for asingle product width and then manually lockedin that position. The fully adjustable unit canaccommodate a variety of product widths by afew turns of the handwheel.

2 For MultiSpan Wedge Units – Use the Table below to determine your Product Familyand the appropriate recommended chain material
NOTE
Determination of recommendedchain material (Step 2) and chainwidth (Step 3) applies only toMultiSpan Wedge Units.MiniLink chain is available in60mm-wide Polyurethane only.
• The decision to select a MiniLink or MultiSpan WedgeUnit is based on 3 factors:
1. Maximum height of your product
2. Maximum running speed of Wedge Unit
3. Total product load in Wedge Unit
Please choose the appropriate Wedge Unit model(MiniLink or MultiSpan) using the table below:

Gapmin = Minimum gap required foryour product
10.85” / 275.6mm 33.85” / 859.8mm
• If your incoming product does notmeet the minimum gap requirements,you may increase the velocity of theWedge Unit to pull the needed gap.Use the basic formula below to findthe necessary velocity of the WedgeUnit.
Vw = VoL + Gapmin
L + Gapi
Vw = Desired velocity of Wedge Unit (fpm / m/min)
NOTESMaximum velocity of a standard MultiSpan Wedge Unit is 180 fpm (55 mpm). Please contact SpanTechif your velocity requirements exceed this limit.

5 Refer to “Dynamic Load Capacity” Charts on the following pages
• The spacing between products (“gap”) is critical to the layout of the Wedge Unit. If thegap is too small, products could contact and interfere with each other through the curves.Use the following formula to determine the minimum gap for your product.

Wedge conveyors must be equipped with a Variable Frequency Drive (VFD) with soft start/stop capability.The VFD can be customer-supplied or provided by SpanTech.
NOTEThe formula at left is suitable
for use with Metric units [mm]or English units [decimal feet].
A special MultiSpan Wedge Unit has been designed specifically for the paper converting industry.Contact SpanTech for more information on this specialized Unit.
Vo = Initial velocity of incoming conveyor (fpm / m/min)
Gapmin = minimum gap required (found in previous step)
Gapi = initial product gap (before entering Wedge Unit)
