Abstract: A check valve for a screw is provided. The check valve includes a retainer tip, operable to be attached to a distal end of a screw shaft, the retainer tip defining at least one melt channel. A first ring is coaxially mounted to and rotationally-coupled with the retainer tip. A second ring is coaxially and slidably mounted to the retainer tip, and is operable to rotate relative to the retainer tip. The second ring is operable to reversibly move between an open position which permits melt to flow through the check valve and a closed position which prevents backflow of the melt.

Abstract: According to embodiments of the present invention, there is provided an adjustment device for adjusting a distance between a take-off plate and a treatment device of a molding system and a method for use thereof. More specifically, there is provided a distance adjustment device configured to adjust a distance between a take-off plate coupled to a fixed platen of a molding system and a treatment device coupled to a movable platen of the molding system. The adjustment device comprises a movable platen engagement interface configured for attachment to the movable platen of the molding system; a plenum engagement interface configured for attachment to the treatment device; a distance adjustment mechanism configured to selectively fix a position of the treatment device relative to the movable platen in a desired position.

Abstract: FIG. 3 illustrates a clamp piston assembly (40) comprising a body portion (44, 46, 48) in which a pocket is provided. The pocket is arranged to receive an insert in the form of a rotatable clamp bushing (48). Sets of blades or wear pads (52, 62) are positioned on both an internal surface (51) of the pocket and the external surface of the clamp bushing (48) and cooperate to form sealable chambers that extend about the circumference of the clamp bushing (48). These chambers are in fluid communication with suitable processor-controlled valves (82, 84) and hydraulic or pneumatic pumps (80) that operative to purge and inject fluid from and into the chambers. Pressurized fluid acting within selected chambers causes rotation of the clamp bushing (54). The insert also contains a row of teeth (58) arranged to selectively engage corresponding teeth (25, 26) in a tie-bar (19, 20).
