Used Automatic Textile Press for sale (32,138)

Condition: good (used), Year of construction: 2006, A versatile 6 section clamping machine specifically designed for solid wood edge and face laminating. The Clamp Carrier is ideal for producing a variety of components such as panels, table tops, block gluings, joinery sections and stair parts. The patented 'equaliser' clamp arms incorporate a number of important features not found on other types of mechanical clamp that help ensure a quality glue joint is produced. As standard the machine is equipped with a hydraulic clamp tightener / loosener, pneumatic component flattener and hydraulic rotation. Equipped with: 302 type clamp arms with 915mm (36") max opening and 95mm ( 3.5") high jaws - 2 x 80S heavy duty hydraulic drives for rotation - 1 x 80V semi automatic hydraulic clamp tightener. (Hydraulic pack 3 phase electrics). - 1 x 80D pneumatic component flattener Fedpfx Aneru Evgjlopk - Pneumatic movement in / out of front rest - CE safety perimeter guards Year - 2006 CE

Condition: new, The Matrix Fast 500 is the latest in the Stromab range of automatic crosscutting machines, with a high speed upstroke saw action which depending on cutting paterns can give up to 40% more production than the standard machine. The machine is primarily designed for programmable and repetitive cutting from standard and / or random lengths of timber. The new high speed pneumatic saw unit with variable speed control, can also be set to limit the saw stroke when cutting smaller boards, helping to increase production even further. The pusher is fitted with a heavy duty rack and pinion drive feeding system, for fast and accurate positioning giving a high level of repeat cutting accuracy, the pusher is raised with a pneumatic cylinder forits return to its loading position, allowing the operator to prepare the next pack of timber on the table without having to wait for the pusher to return to its idle position. The infeed and outfeed tables are of all steel construction meaning even heavy sections or packs of timber can be processed. The saw unit and clamping area is totally enclosed by a clear hinged electrically interlocked hood that while allowing the operator a clear view of the cutting area still gives complete protection. additional safety features include full length guarding of the rear of the pusher system, whilst there is a safety pull cord running along the length of the front infeed table. Programming and entering of cutting lists is simple with the on board Top 12 control unit. With a 12" colour touch screen display, offering a modern, robust and reliable control system with many innovative features and is ideally suited for a factory or workshop environment. As standard the machine now offers USB, ethernet and 3 levels of optimisation including "board sequence" ideal for repetitive cutting. The Matrix OPTI version offers an additional 3 optimisation criterias including "minimum waste" and automatic board length measuring suitable for random length boards. The Matrix DEFECT version offers all optimisation criterias, length measuring, a defect removal camera and timber grading. Additional options also include extended outfeed table, pneumatic side roller pressure, label and inkjet printing. To date we have supplied over 250 Matrix saws in to the UK, with a number of customers installing several machines.
