WEINIG rip saws: Strong solutions to make your cutting even more profitable
Width cutting, generally referred to as ripping, combined with longitudinal cutting, represents the first processing stage in all solid wood processing. Thus, it constitutes the foundations of efficient and modern production. Errors in (width) cutting, such as wood losses, missing quantities or excessive stock levels permeate the entire subsequent production process and have a lasting, negative effect on operating results.
Modern and efficient cutting is, therefore, indispensable. WEINIG provides optimal machine concepts to fulfill this requirement. From the small workshop to the fully-automated production line.

Attack is the best form of defense
Daniel Schläpfer was recently faced with a few challenges. Fifteen years ago, he was able to offset the slump in revenues in the construction industry with high flexibility and expanded production depth. Now, once more, he has taken forward-looking action.
Competition among Swiss sawmills is fierce. Out of 1,500 sawmills that were active in Switzerland around 15 years ago, just 300 remain. Those who want to survive must be flexible and produce profitably. Since the crisis in the construction sector, Scierie de Cornaux on Lac de Neuchatel near legendary ski resort La-Chaux-de-Fonds in Switzerland has increasingly focused on private orders. Now, a good blend of special orders, such as stair treads, as well as a number of major orders, ensures high capacity utilization.
To ensure that business remains strong in the future, Daniel Schläpfer took the decision to modernize his production operation. It was essential for him that the new saw could be used universally – without elaborate and time-consuming pre-setting when changing from one application to the other. Thus, one year ago, he invested in a WEINIG FlexiRip JrionLine longitudinal circular saw of the latest generation. Combined with a compact mechanization concept, the machine runs daily throughout a nine-hour shift.
The new FlexiRip fulfills the objectives of producing more profitably and achieving higher capacities to the complete satisfaction of the sawmill. "It was the right decision. With the FlexiRip, we have laid the foundations for growth and future-proofing," assessed company boss Daniel Schläpfer.

Transatlantic quality alliance
The North American window market is becoming more demanding. A good environment to start a model for the future combining Germany technological know-how with windows "made in USA".
Hurricanes and icy temperatures are nothing unusual in Massachusetts. The ideal environment for production of quality windows with triple glazing. And home to Menck Windows USA Inc., a joint venture of German company Menck, since 2013. With self-produced, energy-efficient window and door components, the company aims to secure a share of the major US market. The signs are promising. Energy-saving standards, certification guidelines and tax incentives have significantly stimulated the window market in the USA. There is particular investment in the prestige market segment. However, high demands from customers require first-class production technology. Little surprise, therefore, that Menck turned to WEINIG. Since the start of the year, its windows have been produced on a Conturex CNC processing center – the first of its kind in the USA. The system is respectfully referred to as a "factory in a shoe box" at Menck USA. The Conturex performs the work of several standard single machines in a single pass. Every two minutes, it produces a new, completely processed part. With a ValuRip, an OptiCut S 90 and a Powermat 1200, Menck has also placed its trust in WEINIG know-how in terms of ripping, cross-cutting and profiling. The entire system is networked via MillVision Pro production software, offering optimal efficiency in production.
Pushed to the limits
Every innovation must pass an acid test at some stage. The new ProfiPress 450 Speed multi-blade buzz saw was not given a VIP pass at Josef Wyss AG in Büron, Switzerland.
A picture-perfect test scenario: The Wyss sawmill produces glulam lamellae, crate and packaging products as well as construction timber. In 2006, the company also invested in a chipper and circular saw line in addition to its reciprocating saw. The slab timber is cut with an edger. The latter was reaching the end of its service life at Wyss. "Repairs were piling up. We were also not sufficiently flexible with our old system," says Stefan Wyss. "As a satisfied customer, we wanted to give WEINIG the opportunity to test its prototype," he adds. In contrast with other machines with a chain bed on the market, the ProfiRip 450 Speed has a roller feed. This is particularly useful for softwood sawmills such as Josef Wyss AG, for whom throughput capacity is a priority. "The objective was not to achieve higher cutting volume," explains Stefan Wyss.
"The advantage of higher added value was much more important to us." The multiple cutting and processing of different widths ensures better use of the raw material. Furthermore, the top saw shaft achieves higher cutting quality. And there are even more plus points for the new machine: "Previously, cutting on the edger was highly inflexible. With the three-fold blade adjustment, we are completely flexible," says Stefan Wyss. Wyss can also process different panel widths interchangeably without having to adjust the system. Conclusion from the test phase: The new ProfiRip 450 Speed is a robust machine for day-to-day sawmill operations that can also achieve high feed speeds.
There is room in the smallest hut
In the timber-rich Italian Puster valley, there are numerous carpenters. This makes differentiation important. Weissteiner does this with a clear strategy that also takes account of the cramped conditions.
Many machines, little room – such is the situation in the Weissteiner father and son workshop.. Despite this, there are never any traffic jams. The completely modernized production facility is a strong process-oriented system with optimal interfaces. Carefully assembled to drive forward the specialization in high-quality solid wood panels. Stefan Weissteiner: "It was important for us to be able to receive everything from a single source and that the machines are equipped with the same user interface," he recalls.
The central component of the system is an OptiCut C 700 cross-cut saw, which performs the heavy cutting. A VarioRip 310 M multi-blade rip saw is responsible for splitting the boards. With its two adjustable saw blades, the machine significantly improves wood recovery. An OptiCut S 50 push-feed saw cuts the lamellae for the solid wood panels. The machine is integrated into the CAD/CAM software and receives all parts lists via the office. A bar code printer ensures perfect part tracking in subsequent processing. Gluing is performed by a ProfiPress L 2500 with high frequency technology. "The compact design of the machines is ideal for our little workshop," says the senior partner. "Unlike previously, we can now also perform glued butt joints and create panels almost free from offsetting." On the market, the WEINIG machine concept has opened up new opportunities for the operation. Other carpenters are interested in solid wood panels but production is only possible with a state-of-the-art machine park. A particular advantage is the flexibility in terms of thickness, length and width and, above all, production in batch sizes of 1.
Ready for the future with solid wood panels.
Since 2001 the hardwood sawmill owner Walter Ohnemus has been running a cutting line. In 2011 he dared to take the next step towards further processing: solid wood board production in Kappel-Grafenhausen with the ProfiPress T 3500 from Dimter.
