ABSTRACT:
A cloth tentering device wherein the tentering force for spreading cloth is produced magnetically between a permanent magnet member accommodated within a tubular cloth or engaged with the selvages of a flat cloth and rows of electromagnets in position separate from and parallel to the cloth. The tentering force can be freely adjusted in the course of the tentering operation by controlling the energizing current of the electromagnets.
