Method Of Winding Up Tampon Material
Patent No. EP4039237 (titled "Method Of Winding Up Tampon Material") was filed by Johnson And Johnson on Dec 30, 2016. The application was issued on Jul 3, 2024.
Patent Summary
A string application and knotter apparatus for applying a withdrawal string to a tampon comprises a substantially rigid circular ring bearing (10) with a mounted string conveyor (12) defining a circular string path. The apparatus interior (13) remains substantially open to facilitate tampon sliver passage. Key components include a snake (14), a hook (16), a knife, and a clamp (18) configured to hold the string's leading end during conveyor travel. In a broader system for high-speed tampon blank manufacturing, the ring bearing defines a plane perpendicular to a sliver guide and gripper motion, and parallel to a winding mandrel's axis. The system further incorporates a sliver guide with a tapered end section, a reciprocating gripper, a winding mandrel, and multiple winding cups.
