Zusammenfassung:	A plastic pallet assembly is formed from plastic lumber by melting sections of runners and cross members and contacting them to join said runners and said cross members to form a pallet. A machine having an assembly table, cross members for supporting and moving pallet runners in a vertical direction, a support table for a pallet cross member, hot plates moveable in a vertical direction and in a horizontal direction for insertion between the runners and the cross member, and a force bar moveable in a vertical direction for applying a force to the runners, hot plates and cross member. A process for producing a plastic lumber pallet in which the runners are placed on a support bar and raised in a vertical direction, a cross member is placed on a support table, hot plates are inserted between the runners and cross member, pressure is applied by means of a force bar and a portion of the runners and cross member is melted after which the hot plate is withdrawn by raising the runners and hot plate and the molten section of the runners and cross member are brought in contact to join the runners and cross member.
