An installation tool and related methods are provided. The tool can pull a strip of collated fasteners along a collated fastener path to a guide, where individual fasteners are sequentially separated from the strip and advanced into a workpiece. The tool can include a tension feeder located downstream of the guide. The tension feeder is configured to apply tension to the strip between the guide and a leading end of the strip. The tool can include a driveshaft configured to attach to a conventional drive tool chuck or a drive tool having hexagonal type drive components. The guide can be one piece and replaceable, with a guide body and a guide head. A strip slot can be defined in the same to align a fastener head with a backstop and facilitate entry of a fastener shank in a feed slot. Related methods of use are provided.

An autofeed attachment (4) for a screw-driving apparatus (2) includes a base casing (30), a feeder casing (32) slidably mounted on the base casing (30) and a wheel (72) rotatably mounted within the feeder casing (32). When rotated in a forward direction, the wheel (72) advances a screw strip (50), which has a plurality of screws (52) coupled by a connecting strip. A wheel forward-direction rotating mechanism (60, 64, 66, 68) rotates the wheel (72) in the forward direction and restricts rotation of the wheel (72) in a reverse direction opposite the forward direction. A wheel-release mechanism (70, 107, 117) releases the restriction placed on rotation of the wheel (72) in the reverse direction. The wheel forward-direction rotating mechanism and the wheel-release mechanism are disposed, at least partially, inside of the wheel (72) and/or the rotational axis of the wheel (72) intersects a release button (107) of the wheel-release mechanism.

A method of installing pre-molded seal caps onto fasteners that extend from a surface comprises sequentially delivering the pre-molded seal caps, arranged on a carrier strip, to a plunger mechanism via a feed system. The method also comprises sequentially removing the pre-molded seal caps from the carrier strip using the plunger mechanism, operating in concert with the feed system. The method further comprises individually installing the pre-molded seal caps onto selected ones of the fasteners using the plunger mechanism.

An apparatus for installing pre-molded seal caps onto fasteners that extend from a surface is disclosed. Apparatus comprises a plunger mechanism, configured to individually install the pre-molded seal caps onto selected ones of the fasteners. Apparatus also comprises a feed system, configured to sequentially deliver the pre-molded seal caps, arranged on a carrier strip, to the plunger mechanism. Apparatus additionally comprises a take-up mechanism, configured to collect the carrier strip as the pre-molded seal caps are sequentially removed from the carrier strip. The plunger mechanism is also configured to operate in concert with the feed system to sequentially remove the pre-molded seal caps from the carrier strip.

An autofeed attachment designed for mounting to a manual-feed screwgun that has a recessed channel on the exterior surface near a protruding flange. The autofeed attachment has at least one movable plate that is forced inward by a ramp structure on the interior surface of a rotatable collar. When the collar is rotated in a predetermined direction, the ramp surface acts to force the movable plate toward the interior, until that movable plate comes into contact into the recessed channel on the screwgun. Once that has occurred, the autofeed attachment will now be locked into place into that recessed channel and behind a protruding flange of the screwgun. The movable plate(s) is positioned between two retainer structures that are spaced-apart from one another, and create a gap through with the at least one movable plate can move during the locking, and later unlocking operations, by twisting the rotatable collar.

A screw rope is configured to hold fixed portions of threaded parts of respective screws so as to be obliquely disposed at predetermined parallel intervals and at a predetermined inclination angle by a belt-shaped member which runs in a length direction and binding strips which are provided on the rear surface side of the belt-shaped member at predetermined intervals, to continuously form a guide groove on the front surface side of the belt-shaped member along a length direction thereof, to dispose many upper recessed parts at a position above the guide groove in a scattered state and over the entire length on the front surface side of the belt-shaped member and to dispose many lower recessed parts at a position under the guide groove in the scattered state and over the entire length.

A staple advance device includes a receptacle having a guide pathway formed by a low level surface, a high level surface, a tilted surface located between the low and the high level surfaces, and an inclined surface formed and located beside the low level surface and communicating with the low level surface, a barrel is slidably engaged in the receptacle, a guide plate is attached to the barrel for supporting the fasteners, an actuating lever is pivotally attached to the barrel with a pivot axle and includes a guide pin slidably engaged in the guide pathway of the receptacle, and a guide rod for feeding the fastener into the barrel selectively, a guide device includes a gate for engaging with the tilted surface and for forming an endless guide pathway for the receptacle selectively.

[Problem] To provide a screw cutting mechanism that can stably feed screws to a driver bit by stabilizing the position of the screws, and that has an accurate and smooth cutting action. [Solution] Provided is a screw cutting mechanism for cutting screws one at a time from a screw feeder, wherein: the cutting mechanism is equipped with a rotating disk that rotates horizontally; the outer circumference of the rotating disk comprises a recessed section that opens toward the axis of rotation and holds the screws therein; the rotating disk fits into a circular cavity in the upper section on the frame side; a rotating shaft attaches the rotating disk to the upper section on the frame side, is equipped with a fixed bearing section in the middle section on the frame side, and is equipped with an adjustable bearing section that can be secured to the lower section on the frame body side so that the attachment position is adjustable; a slit disk, which is equipped with a slit that corresponds to the recessed section, and a drive gear are fixed at suitable locations on the rotating shaft between the adjustable bearing section and the rotating disk; a detection mechanism for detecting the slit of the slit disk is provided; a stepping motor is controlled by a detection signal from the detection mechanism to drive the drive gear; and the rotating disk is rotated by a prescribed angle in one direction.
