Abstract
A converter mechanism for producing low density, pad-like resilient cushioning dunnage product from sheet-like stock material, such as for instance paper, with a separate mobile cart for rotatably mounting a roll of sheet-like stock material thereon in position for feeding the stock material into the converter mechanism. The cart comprises a framework open at its forward end and including spaced upright members, and adapted to receive therebetween in generally snug relation a laterally projecting portion of the converter mechanism for coupling the cart to the converter mechanism especially in a direction transverse of the converter mechanism and cart, and providing for expeditiously positioning the cart and the associated stock roll in proper position adjacent the converter mechanism. The cart comprises a base frame and forward and rearward uprights having cross pieces connecting the respective pair of forward and rearward uprights, and with the forward uprights being of a shorter upwardly projecting height as compared to the height of the rearward uprights.
