Abstract
Bobbin wound coated monofilament tapes where the coating comprises between 20% and 120% by weight of said tape, and the process for bobbin winding coated monofilament dental tapes comprising combining a coating conditioning means with means for winding at substantially constant tensions to produce controlled tension bobbins that do not unwind, that dispense uniformly free from back lashing, and that are substantially free from coating displacement and winding displacement when exposed to high temperatures and high relative humidity and that have tack values from between about 0.1 and about 0.5 grams.
Claims8
In a process for bobbin winding coated monofilament dental tapes,
- wherein the coating comprises two or more coating materials, and wherein the coating amount ranges from between about 20% by weight and about 120% by weight of said tape;
- the improvement comprising:
- employing a coating conditioning means in combination with a decelerating winding speed tape tension control means to maintain essentially constant tension on the coated monofilament tape as it is bobbin wound;
- wherein the conditioning means comprises a controllable heat surface for contacting and warming the coating and the tape to a temperature just below the softening temperature of the coating, prior to bobbin winding.
In a process for bobbin winding coated monofilament dental tapes,
- wherein the coating comprises two or more coating materials, and wherein the coating ranges from between about 20% by weight and about 120% by weight of said tape;
- the improvement comprising:
- employing a coating conditioning means in combination with a decelerating winding speed tape tension control means to maintain essentially constant tension on the coated monofilament tape as it is bobbin wound;
- wherein the coating conditioning means comprises a controllable heating zone through which said coated monofilament tape passes prior to bobbin winding, to warm the coating and the tape to a temperature just below the softening temperature of the coating.
