Cooper Machine Overhead Scragg (with Vertical Edgers)
End-dogging log mills have been a Cooper Machine specialty for 50 years, which is why Cooper is known for being the best Scragg on the market. Cooper Machine offers versions of the Overhead Scragg that are designed to handle logs as small as 3 feet up to 20 feet long, depending on the customer’s specifications. These machines are designed and built to run a long time (with some still in operation over 30 + years) with little maintenance, and with just one person needed to operate the machine. We do this to save you money in the long run. The Overhead Scragg is available with 48” or 56” diameter circle saws. Also available with a Twin Band (see Twin Band Overhead). These machines are available with several options for controls/setworks including: Cooper X/Y Ultrasonic scanning,a Horner PLC/Delta Controller or 3D scanning from Lewis Controls. The Overhead Scragg is available with several upgrades available including three or four saw vertical edgers, graphic display and pivot dog lift for faster loading. Also now available with chipping heads. We will soon be offering upgrades for our existing customers to upgrade to a PLC.
Cooper Machine Skewing Overhead
The Skewing Overhead takes the best of the Standard Overhead and adds some new features that increases both yield and production over the Standard Overhead. Different variations of this machine can handle logs as small as 3 feet up to 20 feet long, depending on the customer’s specifications. Like our Standard Overheads, these machines are designed and built to run a long time with little maintenance, and with just one man needed to operate the machine. We do this to save you money. This machine comes standard with skewing log turners that are able to skew up to 3" left/right. This allows the Overhead to create two equal faces to increase yield on marginal logs and reduce the amount of boards to be edged. The modification to a rear pivot dog lift allows for increased production.
Cooper Machine Conventional Sharp Chain
Cooper Machine offers several versions of the Sharp Chain Scragg. The Standard Sharp Chain uses 100 roller chain with drags to run inside 3 x 4 x 3/8 tubing with 3/8 x 1 AR wear strips. It is built to accommodate smaller diameter (from 3 ½” to 12”) low grade logs with standard feed speeds from 40” to 20’ long. The Sharp Chain Scragg is also available with manual setworks, the Cooper profiling and measuring system or Lewis Controls 3D scanning. This equipment is manufactured from heavy duty steel and parts to create a long lasting machine with low maintenance costs.
Cooper Machine Twin Band Overhead
Twin Bands ranging in sizes 8" up to 12" are available with either the Skewing Overhead or the Standard Overhead. Cooper Machine sells MIT S.A. band saws or we can use the customer's choice. Models are available to cut from 36” up to 20’ in length. This machine is also available with Chipping Heads and can be run with Cooper controls or 3D Scanning (Lewis Controls or your choice).
Cooper Machine Yield Champ
The Yield Champ Scragg is a combination Sharp Chain Scragg and Edger for further processing the cant. It utilitizes an optimized log turner and sharp chain feed system. A great benefit of the Yield champ is it requires minimum man power (only one man is needed to operate both the Sharp Chain Scragg and Edger). Once the log is through the 44”, 48” or 56” diameter saws (depending the customer’s requirements), the cant is rotated 90 degrees and then fed into a second saw(s). There it is cut into a three or four sided cant or into two cants and two slabs with the three saw option. This mill is available with Cooper computer controlled saw setworks (which provides precise cutting of cants) as well as several options depending on customer needs including an infeed deck and slab recovery system. All of this equipment is manufactured from heavy duty steel and parts to create a long lasting machine with low maintenance costs.
Cooper Machine Precision Sharp Chain (Available with Circle Saws or MIT Twin Bands)
Cooper Machine also offers a high quality Precision Sharp Chain that comes with a 140 roller chain t-bar rail sharp chain system for faster production. This system is also available with Cooper Machine's Generation 4 chain with larger drags or Viking Chain.It has a thumper to drive the log down on the chain. This machine is available with either circle saws (see 1st video) or MIT band saws (see 2nd video). The Precision Sharp Chain Scragg is also available with vertical edgers to edge slabs on the Sharp Chain. Or add chipping heads (either Key Knife or Cortex) to chip the slabs on the Scragg. Works great in conjunction with a slab recovery system to recover the slabs. This machine is available with either ABB or Allen Bradley PLC. Starters and VFDs can be quoted as well. All of this equipment is manufactured from heavy duty steel and parts to create a long lasting machine with low maintenance costs.
Cooper Machine Twin Band Skewing Overhead with Chipping Heads
We took our high production Skewing Overhead and MIT 10 inch Band Saw and added Key Knife Chipping Heads and made a masterpiece. This machine can cut hardwoods or softwoods from 5" up to 28" in diameter. Multiple length options are available. This machine has our skewing center system with independent log positioners, ultrasonic sensors for diameter readings of the logs for autoset with manual override (or 3D scanning available), and skewing log turners. There are two wide cant supports (one before and one after the chipping heads). Six head key knife chipping heads with 150hp drive motors and a polychain belt drive. A MIT Twin Band (or customer preference) with 63 inch diameter wheels and 10 inch bands were used on this machine but different size bands and wheels are available. Outfeed consists of 8 inch center beam cant guide with two 22 inch wide belt conveyors. Comes with hydraulics, power unit, a 8 x 8 foot cab, four camera color monitoring system, computer and graphic display.
Cooper Machine Tandem Scragg Saw
Cooper Tandem Scragg is great for smaller diameter logs when you want a lot of production with minimum employees. The Tandem Scragg is comprised of two husk frames, with either 48" or 36" saws. Ultrasonic sensors or lasers for diameter reading of logs for first saw autoset with manual operator override, auto band saw set to make four sided cants. Comes with a Generation 3 Precision Chain Feed using 140 roller chain and hardened t-rail track, 20hp variable speed electric chain drive with VFD climate controlled cab, and four camera color monitoring system. Saw 2 has a minimum 3” saw set. Saw two comes with two 75hp motors and polychain belt drives, 2” induction hardened chrome shafts and linear slide bearings, and temposonic cylinders with sensors and helper cylinders for husk frame autoset (and manual override). The outfeed consists of 6" cant/slab separation wings behind saw, four sets of spring loaded hold-on wings and an 8” H-beam common frame. This machine can be used as a stand alone with one person operating the machine or it can be used in a pallet mill. Pallet mills can vary, but generally used with a slat table to separate the slabs, splitter, trimmer and VSA with just a few people in the whole sawmill.
