Abstract
A nozzle system is provided comprising a nozzle tip supported in a nozzle body with an alignment member. The alignment member has a connection for engaging a corresponding connection located on the nozzle body. The alignment member also has an aperture concentric with the sleeve that has a tapered engagement surface for contacting a tapered engagement surface on the nozzle tip. A first melt channel is defined through the nozzle body and a second melt channel is defined through the nozzle tip. The melt channel in the nozzle tip has a first section that extends along a first axis from an inlet, a second section that extends from the first section at an incline and a third section that extends from the second section parallel to and eccentric with the first axis. The resulting melt channel defines a straight through channel parallel to said first axis from said inlet to said opening.
