Abstract

A nail coil remediation apparatus includes a roller assembly, a rotary holding shaft, and a nail channel assembly. The roller assembly includes sequentially aligned stages, at least one stage interfacing with at least one motor that powers the roller assembly. The stages include an aligning stage that includes a first roller and a helical gear member having multiple teeth, and a straightening stage including a second roller. The rotary holding shaft is configured to support the nail coil and selectively transfer the nail coil to and from the roller assembly. The nail channel assembly includes a slot configured to receive the nail coil from rotary holding shaft and selectively transfer the nail coil through the roller assembly.

Dependent claims

A nail coil remediation apparatus, comprising:

(a) a rotary holding shaft configured to support a nail coil and to rotate bidirectionally to selectively unwind and rewind the nail coil;
(b) a nail channel assembly comprising a slot, wherein the slot is configured to receive and guide a plurality of heads of a plurality of individual nails of the nail coil therethrough;
(c) a helical gear member positioned adjacent to the slot of the nail channel assembly, wherein the helical gear member comprises a plurality of helical teeth spaced apart from one another to define spaces configured to receive the plurality of individual nails of the nail coil between adjacent helical teeth;
and
(d) a first roller positioned relative to the helical gear member, wherein the first roller is configured to force the plurality of individual nails of the nail coil into the spaces between the adjacent helical teeth as the nail coil passes between the first roller and the helical gear member;
wherein the rotary holding shaft is configured to rotate in a first direction to unwind the nail coil and advance the nail coil through the slot and between the first roller and the helical gear member, and wherein the rotary holding shaft is further configured to rotate in a second direction opposite the first direction to pass the nail coil back between the first roller and the helical gear member and rewind the nail coil onto the rotary holding shaft.

3 more elements

A nail coil remediation apparatus, comprising:

(a) a frame configured to support and house components of the system;
(b) a rotary holding shaft supported by the frame, wherein the rotary holding shaft is configured to support the nail coil and to rotate to unwind and rewind the nail coil;
(c) a nail channel assembly supported by the frame, wherein the nail channel assembly is configured to receive the nail coil from the rotary holding shaft and guide the nail coil therethrough;
(d) a roller assembly supported by the frame and positioned adjacent to the nail channel assembly, wherein the roller assembly comprises:
(i) a gear member comprising a plurality of teeth defining spaces therebetween configured to receive individual nails of the nail coil;
and
(ii) at least one roller positioned relative to the gear member, wherein the nail coil passes between the at least one roller and the gear member, wherein the at least one roller is configured to guide the individual nails of the nail coil into the spaces of the gear member;
and
(e) at least one motor operatively connected to the roller assembly, wherein the at least one motor is configured to drive the roller assembly;
wherein the rotary holding shaft is configured to rotate bidirectionally to pass the nail coil through the roller assembly in a first direction and a second direction to remediate alignment of the individual nails of the nail coil.
