MACHINING TECHNOLOGY Altendorf saw safety wins German Technology Award Germany-based Altendorf GmbH won over a 12-member jury with its novel safety system for sliding table saws in the category “Industry and Crafts.” This is an important area of development as a workers’ hands are only a few centimeters away from the high-speed rotating saw blade when they guide workpieces during sawing operations. Every day around the world, work-related accidents occur when various materials are cut using sliding table saws. For the most part, commonly known protection systems use technology that relies on the conductivity of skin to detect a hazardous situation and to then pulsate the saw blade to a stop. The problem with this approach: All existing solutions require that contact between the saw blade and hand takes place for the safety system to kick in. In some systems, the machine’s internal components are damaged to prevent continuation of work after the incident. Early hazard detection is critical Altendorf’s system relies on the ability to detect the hazard at a very early stage. Various defined situations are optically detected and classified. For this, two cameras collect data which is then processed by a powerful handdetection program. When the system identifies a dangerous situation, the hazard is eliminated: Within a quarter of a second the whole saw unit quickly slows down and the saw blade abruptly stops. After the safety assistant has been activated, the machine can immediately go back to work. No damage to the machine or saw blade occurs and the productivity of operations remains intact. Karl-Friedrich Schröder, Head of Development at the Altendorf Group, explains the motivation for the ground-breaking development: “We’ve always been uneasy about the fact that existing systems only ever kick in after the accident has happened. And they cause damage to parts of the machine as well. We wanted the machine to act sooner, first and foremost to prevent accidents – that is, to protect the operator. So we developed a system that gains us valuable time, one that enables us to disable the danger before contact even happens.” Honored for innovation power As jury spokesperson, Thomas Niehoff, General Manager of the Chamber of Commerce of East Westphalia, Bielefeld, outlined the jury’s reasons for their award decision. In his remarks, Niehoff highlighted the innovation power of the machine manufacturer’s longterm development work: “In the view of the jury, Altendorf’s many years of development work has successfully produced the next level of innovation in table saw safety. This will lead to setting new standards that will improve requirements for worker safety in the woodworking industry and the trades worldwide. At the same time, the company is effectively positioning itself in global competition. With its safety system, Altendorf will significantly boost sales and safeguard jobs.” www.altendorf-handguard.com Pallmann-Size reduction technology for the perfect particleboard New order for Pallmann Maschinenfabrik GmbH, the size reduction specialist within the Siempelkamp Group: In August, Merino Industry Ltd., one of the leading laminate producers in India, placed an order for several machines from Pallmann’s portfolio. The order volume consists of three knife ring flakers, two double stream mills and a re-chipper as well as the supervision of commissioning. The machines are part of a new particleboard plant at Halol in the state of Gujarat: Merino Industry Ltd. founded in 1974, primarily focuses on the production of premium quality laminates, however, with the new plant, they will also start production of the carrier material. Excellence, maximizing the product value, is firmly established in the corporate motto of the company. The Pallmann-flake preparation ensures quality, especially in the surface layers of the board, which is an indispensable prerequisite for the downstream finishing process. Three knife ring flakers, type PZKR 16-600 guarantee highest flake quality, a high throughput capacity, quick knife ring exchange and precise knife adjustment. Two double stream mills, type PSKM 14-660 produce homogeneous fine flakes with a low percentage of dust and coarse material – ideal for the production of high quality particleboards which have to meet highest demands on surface quality. Merino Industry Ltd. also placed an order for a re-chipper which ensures an economic size reduction of oversized wood chips. The delivery of the Pallmann machines is scheduled for March 2022.

MACHINING TECHNOLOGY New equipment variants ensure even greater flexibility and efficiency Fast, clean change between EVA and PUR hot-melt glues At HOMAG, EVA and PUR hot-melt glues are processed on the same machines and with the same application unit. A new feature is that the glue can be changed via the melting unit without mixing, i.e. with no cross-contamination and no cleaning. Simple removal of the EVA interchangeable container from the melting unit fiLine and, from October, also for EDGETEQ S-500 | S-500 profiLine series. www.homag.com WIN_2019.pdf 24 15.02.2019 13:55:48 Interchangeable containers for easy application of EVA and PUR Due to its resistance to humidity and heat, PUR is ideal for use with edge banding for furniture in humid rooms such as bathrooms, kitchens and laboratories. If these properties are not necessary to achieve perfect edges, the carpenter will prefer EVA for reasons of cost. To facilitate fast switching between EVA and PUR, the HOMAG melting unit can now also be used for EVA. This is thanks to two differently designed, interchangeable containers. Melting unit for EVA and PUR The interchangeable container design used up to now has proven to be an excellent choice for the processing of PUR cartridges. The new interchangeable container is specially designed C for the metered supply of EVA granulate. The M ergonomically designed handles allow the interchangeable containers to be removed from Y or inserted into the melting unit quickly and CM easily. When changing between EVA and PUR, MY no time-consuming cleaning is required. In addition, the application unit can either be replaced without cleaning the machine or simply CY CMY emptied and refilled in the machine. There are three versions available: One for processing both EVA and PUR alternately (new), one for exclusively processing EVA (new) or—as before—one for exclusively processing PUR. Glue change via the melting unit is available for the EDGETEQ S-240 (from model 1240 FC), EDGETEQ S-300, EDGETEQ S-380 | S-380 pro- K Less energy, more power!
