    • An improved mandrel (l0) for use with a weaving loom (l2) for the formation of loops (l6) of a looped fabric suitable for use as a surface-type fastener generally known as a loop-and-hook fastener. The mandrel (l0) has a generally V-shaped first recess (2l) defined in an upper longitudinal edge (22) thereof and adapted to be disposed adjacent to the fell (l5) of a foundation fabric (l2) while being woven on the loom (l2), for receiving individual loops (l6) therein before they are tensioned on a loop-setting portion (20). Since all the loops (l6) are received in the recess (2l) irrespective of their initial looping positions, a warp thread (l7) forming loops (l6) does not interfere with a weft thread (l4) forming a part of the foundation fabric (l2) and the loops are placed in a desired upstanding position when tensioned on the loop-setting portion (20). The loop-setting portion (20) has a second recess (26) defined in a lower longitudinal edge (27) of the mandrel and extending along a limited longitudinal part of the loop-setting portion (20) for releasing the tension on the loops to thereby prevent the loops (20) from being deformed or twised under undue frictional forces applied thereto as they advance along the loop-setting portion (20).
