A device that permits the rapid removal of fiber glass roving from a coil thereof, for movement of the roving to a chopping and spraying gun, wherein the device provides considerable drag to the roving when it is no longer pulled firmly. The device includes a tube that is pivotally mounted on a support, so that the tube can pivot to best align itself with roving moving, therethrough, and then can pivot away from that orientation to cause the roving to undergo sharper bends in passing into and out of the tube, so as to apply braking forces to the roving. The support for the tube can include a pair of rods that fit closely within the corners of a standard roving box, and can also include clamps on the rods that clamp to the box, for facilitating mounting of the tube.
