Fastener strip with discrete magnetically attractable area, and method and apparatus of making same

A fastening device comprising:

• (a) a base;
• (b) at least one fastening element disposed on a surface of the base;
• and
• (c) a magnetically attractable body disposed on the surface of the base on which the at least one fastening element is disposed, the magnetically attractable body having an elongated shape in a longitudinal direction of the base;
• wherein the magnetically attractable body is provided in line in the longitudinal direction of the base, and
• wherein the magnetically attractable body disposed on the base is configured by at least one continuous row of synthetic resin protrusions including magnetically attractable material, and
• wherein the fastening device can be magnetically secured to an object, and
• wherein the protrusions are configured in such a manner that valley portions are formed at predetermined intervals along the longitudinal direction of the base, and
• wherein a long magnetically attractable material is exposed on said valley portions of the protrusions.
