Benefits
Dimensional Accuracy
As winding operations become increasingly automated, accuracy of carrier dimension becomes vital. Machinery manufacturers’ manuals specify that the yarn carrier is made to a tolerance of +/- 1 mm in length and +/- 0.25 mm in inside diameter at both top and bottom of the carrier. These tolerances are critical to the operation of the machines in order to achieve targeted efficiency. Our paper yarn carriers are made and guaranteed to these tolerances.
Balanced – Round
The yarn carrier must be round. The faster the take up speed, the more bouncing will occur. Bouncing at the time of start up causes fiber latching in the yarn that results in an irregular, jerky offwind and poor yarn transfer. An oval carrier also contributes to poor tension control in the beginning of the yarn package formation that allows the yarn to slough instead of transfer. Our technology ensures round carriers every time.
Yarn Identification
Trying to identify yarn packages by color alone can cause problems especially in poorly lit areas. We have an innovative system in which we offer a choice of colors plus easily recognize patterns to enhance the customer’s creative identification program. Custom printing is available for both inside and outside of yarn carrier. The printing can include the yarn producer’s name, company logo, yarn identification and origin. Our customers can often reduce the high cost of labeling by utilizing this feature.
Features
Grooves
Reserve Groove for yarn tail placement is available as well as other grooves for special needs.
Notches
V, Y, U, I and double notches are available to customer’s specifications.
Pro-Fit®
The innovative Pro-Fit® Bullnose is designed to increase your paper carrier winding performance on modern high-speed winders and spinning frames that require a perfect fit.
ANTI-NESTING RIB®
The ANTI-NESTING RIB® reduces wall-to-wall friction of nested paper cones and therefore eases the process of separating the cones. It also reduces potential repetitive motion injury and minimizes machine downtime.
Softuck® (CMI)
Softuck® softens the inside edge of the paper cone for certain take up units to prevent yarn tail loss.
S.G.O.B®
A feathered edge at the base of the paper yarn carrier to prevent yarn tail loss on specific rotor spinning applications.
Surface - Cones
A very important feature of any yarn carrier is the outside surface that holds and protects the quality of yarn being produced. Some carriers have a flocked surface. The flocking material is a manmade fiber that has been glued to the surface of the carriers.
At the startup of a flocked carrier, some of the fibers immediately fly into the air and settle on the bearings of the take up unit, causing excessive and expensive wear.
Additionally, this loose fiber often lingers in the air and can be inhaled by operators. We have also seen fiber from flocked carriers mingle with cotton yarns causing small undyed spots in fabric made with this yarn.
The PLUSH® surface on Conitex Sonoco paper yarn carriers utilizes the paper’s fibers to generate a soft, clean surface that protects the yarn quality and provides excellent holding properties for proper startup. There are no loose fibers to be concerned about.
For special requirements, we also offer surface treatments such as flocking, brushing and spraying.
Surface - Tubes
We manufacture paper tubes with surfaces designed for the particular yarn process the customer is using.
Rotor spinning responds best to a regular PLUSH® paper finish surface that not only properly holds the yarn in place but is also suitable for printing colors and designs.
Air Jet Spinning, due to the configuration of the tube holder, requires outside lining with either kraft finish paper or greaseproof paper, along with startup grooves or slots.
Specialty Cones
Perforated Surface Cones
Optional perforated surface of cones to optimize the steaming of yarn process, providing more value to customer.
Flocked – Brushing – Spraying Surface Cones
These cones are coated by Highest Grade Flocking powder either on the entire Yarn Winding area or Bonded Critical areas. This coating provides a Smooth Feather like Finish on the Cones thereby providing a barrier to minimize the absorption of coning oil by the paper.
Flocked Surface Features:
- Suitable for Rayon, Nylon and other fine filament yarns
- Smooth Feather like Finish
- Optimum Quality
- Highly Durable
Special Micro Cones
For special customer needs, we provide special small size cones with high precision and specially made materials to ensure strength and balance for rotation and load during processing at the customer.
