A method of sealing a wiring-harness, said method comprising: providing an apparatus configured to feed the wiring-harness through a sealing-process, wherein the sealing-process includes the steps of: a) dispensing, with a dispensing-device, a length of a sealing-tape onto a platform along a longitudinal-axis of the platform, the sealing-tape having a first-surface and a second-surface opposite the first-surface, the second-surface in contact with the platform; b) separating a plurality of wire-cables from a portion of the wiring-harness with a separation-device, the separation-device configured to retain the plurality of wire-cables such that the plurality of wire-cables are generally parallel and evenly spaced; c) applying, with a handling-device, the separated plurality of wire-cables to the first-surface of the sealing-tape along a lateral-axis of the platform, the lateral-axis orthogonal to the longitudinal-axis; the separated plurality of wire-cables applied over generally a first-half of the length of the sealing-tape; d) folding, with a folding-device, a second-half of the sealing-tape over the separated plurality of wire-cables such that the second-half overlays the first-half; e) pressing the second-half of the sealing-tape along a vertical-axis of the platform, with a pressing-device, the vertical-axis orthogonal to both the longitudinal-axis and the lateral-axis, such that the second-half contacts the first-half between the separated plurality of wire-cables, thereby forming a cable-band; f) coiling the cable-band along the longitudinal-axis into a generally cylindrical-shaped seal, with a coiling-device, such that the second-surface of the sealing-tape is in direct contact with the first-surface of the sealing-tape; and g) compressing the cylindrical-shaped seal isostatically, with the coiling-device, such that interstitial-voids within the cylindrical-shaped seal are reduced in size. a) dispensing, with a dispensing-device, a length of a sealing-tape onto a platform along a longitudinal-axis of the platform, the sealing-tape having a first-surface and a second-surface opposite the first-surface, the second-surface in contact with the platform; b) separating a plurality of wire-cables from a portion of the wiring-harness with a separation-device, the separation-device configured to retain the plurality of wire-cables such that the plurality of wire-cables are generally parallel and evenly spaced; c) applying, with a handling-device, the separated plurality of wire-cables to the first-surface of the sealing-tape along a lateral-axis of the platform, the lateral-axis orthogonal to the longitudinal-axis; the separated plurality of wire-cables applied over generally a first-half of the length of the sealing-tape; d) folding, with a folding-device, a second-half of the sealing-tape over the separated plurality of wire-cables such that the second-half overlays the first-half; e) pressing the second-half of the sealing-tape along a vertical-axis of the platform, with a pressing-device, the vertical-axis orthogonal to both the longitudinal-axis and the lateral-axis, such that the second-half contacts the first-half between the separated plurality of wire-cables, thereby forming a cable-band; f) coiling the cable-band along the longitudinal-axis into a generally cylindrical-shaped seal, with a coiling-device, such that the second-surface of the sealing-tape is in direct contact with the first-surface of the sealing-tape; and g) compressing the cylindrical-shaped seal isostatically, with the coiling-device, such that interstitial-voids within the cylindrical-shaped seal are reduced in size.
