Abstract: A pallet stacking assembly line having at least two pick-and-place robots are used. The first robot has a relatively low position. The second robot is in an elevated position. A pallet dispenser dispenses a first pallet onto a pallet conveyor The pallet conveyor moves the first pallet to a first build position in front of the first robot. The first robot picks products from a first pick position and stacks them on the first pallet. Once the stack of products on the first pallet reach approximately half the finished stack height, the pallet conveyor carries the first pallet to a second build position in front of the second robot. At the same time, the pallet dispenser dispenses a second pallet which is carried to the first build position. The second robot picks products from a second pick position and places them on the upper portion of the stack on the first pallet to complete the stack. Meanwhile, the first robot is picking and placing products on the lower portion of the second pallet.

Abstract: A process for hydro-entangling a layer of fibers into a web includes the steps of conveying a web from a supply to lie against a traveling hydro-entangling fabric. A layer of fibers is deposited onto a traveling forming fabric, the forming fabric supporting the fiber layer from below. The forming fabric and the hydro-entangling fabric converge at a combining location where the forming fabric and hydro-entangling fabric orient and travel adjacent each other such that the fiber layer and web are sandwiched between the forming fabric and the hydro-entangling fabric with the fiber layer supported from below by the hydro-entangling fabric and web. The forming fabric is separated from the fiber layer after the web and overlying fiber layer are supported from below by the hydro-entangling fabric and the hydro-entangling fabric is conveyed through a hydro-entangling station to hydro-entangle the fibers into the web.
