NineSigma’s client, Bjerrum Nielsen A/S is a leading company in the field of industrial wet paint and surface treatment of substrates such as plastic, wood, metals. One of the core activities of Bjerrum Nielsen is the mounting of fabrics on frames. These frames can be made of metal, wood (e.g. MDF) or plastics (e.g. ABS). The frames are used in applications such as furniture, loudspeakers or other acoustic solutions.
Currently, Bjerrum Nielsen are using a semi-automated mounting process comprising 3 phases:
- First, a double-sided adhesive (tape) is placed manually on the back of the frame. At this stage, it is important that the outside of the tape does not yet adhere
- Next, the fabric is manually stretched around the frame to which the adhesive has been applied earlier
- Finally, a robot welds the tape through the fabric on the back of the frame. It is the welding that activates the outside of the tape, keeping the fabric in place.
Bjerrum Nielsen is looking for alternative solutions for the fixation of fabrics to different materials such as plastic, wood and metal. Primarily, they are looking for a material that can serve as an alternative to the double-sided adhesive that sticks at both sides, from the beginning.
Secondly, in the ideal case, the application of the adhesive, the stretching of the fabric, and the welding of the adhesive should be fully automated.
Bjerrum Nielsen is open for a complete solution, but partial solutions are appreciated as well.
Anticipated Project Phases
Phase 1 – Evaluation of proposed materials and technologies (3 months)
Phase 2 – Implementation into the production process (up to 12 months)
