Abstract
Various embodiments of the present disclosure provide a coil-wrapping system (30) that simultaneously employs separate multiple film rolls (FR1, FR2) to simultaneously wrap separate films around a single coil while the coil is rotated about its longitudinal axis.
Claims13
A coil-wrapping apparatus comprising:
- a machine frame;
- a first wrapper supported by the machine frame and comprising first and second applicator arms;
- a second wrapper supported by the machine frame opposite the first wrapper and comprising third and fourth applicator arms, wherein a coil-wrapping area is defined between the first and second wrappers;
- and
- a controller operably connected to the first and second wrappers and configured to cause the first and second wrappers to simultaneously use first and second film rolls to simultaneously wrap first and second films from the first and second film rolls onto a coil positioned in the coil-wrapping area while the coil is rotated about a longitudinal axis of the coil by:
- causing the first and fourth applicator arms to move the first film roll through an eye of the coil and around an outer surface of the coil in multiple loops to wrap the first film onto the coil;
- and
- causing the second and third applicator arms to move the second film roll through the eye of the coil and around the outer surface of the coil in multiple loops to wrap the second film onto the coil.

A method of wrapping a coil with first film from a first film roll and second film from a second film roll, the method comprising:
- rotating the coil about a longitudinal axis of the coil;
- and
- while the coil is rotating about its longitudinal axis, simultaneously using the first and second film rolls to wrap the first and second films onto the coil by simultaneously:
- moving the first film roll through an eye of the coil and around an outer surface of the coil in multiple loops to wrap the first film onto the coil by periodically transferring the first film roll between a first applicator arm and a fourth applicator arm;
- and
- moving the second film roll through the eye of the coil and around the outer surface of the coil in multiple loops to wrap the second film onto the coil by periodically transferring the second film roll between a second applicator arm and a third applicator arm.
