Abstract: A fastening device molded of a synthetic resin material and adapted to be engaged with a large number of loops on one surface of a fastener part of a mating member includes a base member having on its one surface a large number of hooks integrally molded with the base member and arranged in a plurality of rows. The hooks in each hook row generally have the same hook direction aligned with an axis of the hook row, and the hooks in one hook row and the hooks in an adjacent hook row do not always have the same hook direction. At least one hook in each hook row which is adjacent to a peripheral edge of the base member have a hook direction facing outwardly away from the peripheral edge. With this arrangement, the hooks located adjacent to the peripheral edge are capable of withstand undue force tending to fatigue and eventually break the hooks.

Abstract: At least one, preferably two or more, reels are coaxially mounted on a carriage such as a handcart for rotation independently of each other in order to wind surface type fastener tapes or like strips to be transported from one processing station to another. Disposed in a preassigned position, a driving and braking mechanism comprises a plurality of carrier arms each medially pivoted on a fixed support for oscillation about an axis parallel to the axis of the reels. Each carrier arm has a drive roll and a brake mounted on its opposite ends. As the carrier arm is oscillated as by a fluid actuated cylinder, the drive roll and the brake roll are alternately movable into and out of frictional engagement with the periphery of the flange of one associated reel. Thus, for winding one or more strips on one or more reels, the associated carrier arm or arms may be swung in a direction required to move the drive roll or rolls thereon into driving engagement with the reel or reels.
