Driving disk for floor cleaning machine for arrangement of cleaning- or polishing pad to clean e.g. industrial floor, has adhesive coating laser welded with disk at inner and outer end regions of coating along extensively closed lines

摘要

The disk (10) has an adhesive coating (15) i.e. check plate, provided at a lower side of the disk. The adhesive coating and the disk are formed from laser beam permeable plastic material, and/or laser beam absorbing plastic material. The coating is laser welded with the disk at inner and outer end regions (16, 18) of the coating along extensively closed lines (20, 22). The coating is formed from highly-modified polypropylene, and the disk is formed of laser beam absorbing polypropylene-homopolymer.
