The “PLT B Ladder” Series of welding lines ensure reliable operation and cost-effective production of ladder type “S”-spacers from coils. The sophisticated design of each part of the machine together with the compact layout, allows minimal adjustments for the different parts sizes and also long maintenance intervals.
The machine –depending on the version- can produce spacers with either two or three line wires. Programmable line wire feeding allows variable cross wire spacing within the same spacer. The “T”-type-welding heads produce “T” welded spacers, which can be perfectly stacked in compact bundles, without the need of turning as the conventional “S”-spacers with overlap welding.
Significant material savings: For example at the 100 mm “S”-spacers 22 % up to 33 % of the material of the vertical spacer wires are saved thanks to the “T”-welding. The unique bending system (patented) ensures excellent repeatability, perfect product geometry and works in-line with the welding operation in order to eliminate the idle times during production. The bending system uses synchronized pneumatically operated bending units. Incorporated on the bending system, a flexible automatic stacking unit is used to produce bundles of the programmed quantity of strip spacers, during production.
Successful application in several countries
In order to provide a total automatic solution to the production of strip spacers, the PLT B Ladder welding machines are equipped with an automatic bundling and strapping station, which is fully synchronized with the operation of the welding machine and any disruptions on the production flow during the bundling process are avoided. The ready-strapped bundles are transferred automatically on to a bundle buffer table.
The machine offers highest flexibility in production, which results in significant reduction of the needed floor space for storage of the various product sizes. Thanks to the sophisticated control systems, the machine operates practically unsupervised. The operator is needed only to feed the machine with new coils and to remove from time-to-time the ready-strapped bundles from the buffer table. Numerous machines are already successfully in operation in Germany, Belgium, Czech Republic, Poland, USA and Brazil.
