Method and apparatus for packaging linear material

The method of producing and packaging a bundle of continuous mineral filaments including:

• a. flowing streams of heat-softened mineral material from a supply;
• b. attenuating the streams of material into continuous filaments and gathering the filaments to form a bundle;
• c. rotating a first collet having a package collection region and a temporary collection region;
• d. winding the bundle on the collection region of the first collet;
• e. rotating a second collet having a package collection region and a temporary collection region, the second collet including a fixed member and a circumferential groove having a generally frusto-conical surface in the temporary collection region. adapted to guide the bundle to the fixed member for engagement thereon during transfer of the bundle from the first to the second collet;
• f. laterally moving the advancing bundle along the first collet from the package collection region to the temporary collection region;
• g. contacting the bundle advancing to the first collet with the second rotating collet in the circumferential groove of the temporary collection region such that the bundle is guided by the guide surface into engagement with the member so that the bundle is moved with the member to thereby begin collection of the bundle in the temporary collection region of the second collet.

The method of forming and packaging a strand of continuous glass filaments including the steps of:

• a. flowing streams of heat-softened glass from a supply;
• b. attenuating the streams of glass into continuous filaments and gathering the filaments to form a strand;
• c. rotating a first collet having a package collection region and a temporary collection region;
• d. winding the strand on the collection region of the first collet;
• e. rotating a second collet having a package collection region and a temporary collection region, the second collet having a free end including the temporary collection region, the second collet including in the temporary collection region a fixed member and a circumferential groove having a generally frusto-conical guide surface adapted to guide the strand to the fixed member for engagement thereon during transfer of the strand from the first to the second collet;
• f. laterally moving the advancing strand along the first collet from the package collection region to the temporary collection region;
• g. contacting the strand advancing to the first collet with the second rotating collet in the circumferential groove of the temporary collection region such that the strand is guided by the guide surface into engagement with the member so that the strand is moved with the member to thereby begin collection of the strand in the temporary collection region of the second collet and to sever the strand between the collets;
• and
• h. laterally moving the strand along the second collet from the temporary collection region to the collection region to begin package formation.

An apparatus for collecting linear material from a supply into wound packages comprising;

• a. means for rotating a first collet having a package collection region and a temporary collection region;
• b. means for winding the linear material on the package collection region of the first collet;
• c. means for rotating a second collet having a package collection region and a temporary collection region, the second collet including in the temporary collection region a circumferential groove having a substantially frusto-conical guide surface and a fixed member, said frusto-conical guide surface adapted to guide the linear material to the fixed member for engagement therewith during transfer of the material from the first to the second collet;
• d. means engageable with the linear material for laterally moving the advancing material along the first collet from the package collection region to the temporary collection region;
• and
• e. means for contacting the linear material advancing to the first collet with the second rotating collet in the circumferential groove of the temporary collection region such that the material is guided by the frusto-conical surface into engagement with the member so that the linear material is moved with the member to thereby begin collection of the material in the temporary collection region of the second collet.

• e. means for rotating a second collet having a package collection region and a temporary collection region, the second collet having a free end including the temporary collection region, the second collet at the temporary collection region having a circumferential groove with a substantially frusto-conical guide surface and a fixed member, the guide surface of the circumferential groove adapted to guide the strand to the fixed member for engagement therewith during transfer of the strand from the first to the second collet;
• f. strand engaging means for laterally moving the advancing strand along the first collet from the package collection region to the temporary collection region;
• and
• g. means for contacting the strand advancing to the first collet with the second rotating collet in the circumferential groove of the temporary collection region such that the strand is guided by the groove into engagement with the member so that the strand is moved with the member to thereby begin collection of the strand in the temporary collection region of the second collet;
• said strand engaging means being movable to a position whereby the strand is moved along the second collet from the temporary collection region to the package collection region to begin package formation.
