Abstract
Abstract A remotely controllable device for shooting fiberboard spacers, one at a time, between a selected slit web or strip and its coil, which strip is slit with other strips from a wider sheet or web. The shooting device is horizontally pivoted on a carriage movable along a boom, which boom is swingable about a vertical axis into and out of position under the strips or slit webs being recoiled. The device contains a magazine for storing a plurality of fiberboard spacers which are selectively fed between fast rotating rollers that shoot the spacers between the strip and its coil thereof. A control panel is provided for raising and lowering the spacer projecting end of the device to correspond with the increased diameter of the rewound strip coils, and to move the device along the boom across the parallel strips to select the strip or strips that are sagging and require spacers to make them taut as the other strips are taut as these strips are simultaneously wound on a common mandrel of the recoiler. The projecting end of the device may be provided with a beam of light for indicating its position with respect to each strip coil requiring a spacer. Also when coils are being changed, the device and its boom may be swung out of position, from between the splitter and the recoiler, about a vertical post located on one side of the split webs or strips.
