Easy-Set Multihead Truss Press
Production Description
The Easy-Set Multi-Head press combines the rapid pressing cycle of multi head presses, with the speed and ease of setup associated with the popular Flo-jig Systems. Flo-jigs have been the main production facility of many truss plants, as they can readily handle a wide variety of truss shapes.
The Easy-Set Multi-Head press has been developed for short production runs and is capable of efficiently manufacturing many of the more complex truss shapes for which conventional multihead presses are not suitable. Generally, multi head presses have not been considered suitable for production runs of 10 trusses or less. However, on the Easy-Set, with quick action air clamps and measuring tapes incorporated in the jig, truss runs of one or two are feasible.
The production cycle time is also improved compared with other multi heads, as the Easy-Set Multi-Head press incorporates nail plate placement. Typically, cycle time for an A Type truss, including placing of timber and unloading finished truss, is 50 seconds. The flow of material to the press and the removal of finished trusses will determine the overall productivity of the machine.

Specifications
Configuration - C-Frame press heads each mounted on an individual carriage. Carriage is manually orientated and moved along steel rails to the truss panel point. Cartridge on press head for automatic feeding of nail plates. All hoses and cabling under timber floor.
- Maximum span of truss: 14m (or customer specified).
- Maximum height of truss: 3310mm.
- This press is able to press any truss that has all its panel points joining with a chord.
- Any truss with internal plates cannot be pressed.
- Any truss that has plates that require more than 25 Tonne pressing force cannot be pressed.
- Any joint that is closer than 400mm from an adjacent joint cannot be pressed.
- Commonly installed with a Gantry Press, this allows larger plates, internal joints and plates that are close together to be pressed.
Truss Information
- 5 press heads.
- 30 Tonne press heads.
Options
Extra optional automatic nail plate feeders, which have an adjustable magazine with thumb screw adjustment and will fit most size nail plates up to 150 x 150. MiTek does not recommend the use of auto nail feed on very small plates used at T1 points, as the positioning of these points creep, depending on variation in tolerance of timber sizes and accuracy of sawing. Where unusual plate locations are required, the auto nail plate feed can be simply turned off as required, and the nail plates placed manually.
Owen Easyset Multi-Head Jack-Jig
The Easyset Multi-head Jack-jig has been designed specifically for the fast manufacture of hip and jack trusses. This machine incorporates several features which provide an advantage over production of similar trusses using table presses or drop hammers.
A specially designed jig is used incorporating a fixed bottom chord rail and top chord rail that is adjusted in a few seconds to the pitch and span of the truss. This ensures that all trusses in a job are speedily setup up and retain the same shape. Multiple C-frame press heads can be positioned as required anywhere along the jig rails enabling all nail plates at every panel point to be pressed simultaneously. Operators are not required to handle nail plates during the truss setup and pressing processes. Nail plate cartridges and feeding system are used to automatically position nail plates on the press platens in readiness for the next press.
