Introduction of Lapping Technology
We are expanding our range with the new field of lapping. This is a surface processing process for workpieces with high process reliability and the highest surface quality, while also achieving excellent flatness.
1952
Robert Kettenbaum übernahm mit joke die Vertretung für die DIPROFIL® Handfeilmaschinen.
Bis heute sind die Maschinen ein fester Bestandteil des joke Sortiments und gehören zur Grundausstattung eines jeden Polierarbeitsplatzes. Im Laufe der 50er Jahre entwickelte sich um das Duo aus JOKEFLEX® Hängemotor und DIPROFIL® Handfeilmaschine ein zunehmend ausgefeilteres Programm für Produkte zur Oberflächenbearbeitung.
1940
The abbreviated company name that is still known today was derived from the initials of the company's founders. Kettenbaum developed and built welding devices, laying the foundation for the well-known joke reputation in the field of welding technology that extends beyond borders. Eventually, the commitment expanded to serving tool-manufacturing companies and, especially, mold construction with innovative solutions and countless accessories. This marked the birth of joke's competence in surface technology.
1947
Everyone was involved if you wanted to load a welding machine from joke in the early years. The 12 1/2 kVA resistance welding machine was the company's pride and joy. Thanks to innovative control, JOKE® quickly took a leading position in spot welding. Today, with joke multiSpot 3, we weld the finest spots and seams onto the material.
Gründung
The daring man with his photography boxes: That's actually how the success story of joke began. Because a young man who realized the idea of building cameras out of old cigar boxes that worked really well had to make quite a remarkable journey in life. The man's name was Robert Kettenbaum, he studied electrical engineering and took the step towards entrepreneurship in 1940 with a repair business. That's how joke was founded: For half a decade, the Cologne-based electrical merchant Josef Joisten was a co-founder and partner in the venture.
