Abstract
A matrix rewinder includes a spider assembly having a spider drive shaft, a central hub thereon, a plurality of angularly spaced guide rods extending radially outward from the hub, a mounting block slidably mounted on each guide rod pair for radial movement, a mandrel rotatably mounted to each mounting block, and a drive motor for rotating the spider drive shaft; a mandrel drive shaft mounted coaxially with the spider drive shaft; a mandrel drive motor for rotating the mandrel drive shaft independently of the spider drive shaft to drivingly engage a first core removably mounted on the first mandrel at a first position to wind a web matrix on the first core; a cam track for guiding a second core removably mounted on a second mandrel into driving engagement with the mandrel drive shaft; a sensor sensing a diameter of the web matrix on the first core at the first position, and controlling the spider drive motor to move the second core into engagement with the web matrix when the web matrix wound on the first core at the first position has reached a predetermined diameter; and a knife assembly for cutting the web matrix extending between the first and second cores when the spider drive shaft moves the second core on the second mandrel into engagement with the web matrix such that the web matrix is then wound on the second core which has been then moved to the first position.
