Pattern Matching, Part Four
The CFI installation guidelines are a valuable tool. The CFI Installation Resource Manual provides detailed information concerning measuring patterns, pattern repeats and determining an accurate pattern count. ALWAYS refer to manufacturer's guidelines for installation techniques.
If the pattern count does not match full breadth
If the manufacturer did NOT allow for full repeats across the entire breadth or if the pattern repeat does not meet manufacturing specifications, it is possible that an insufficient amount of carpet is available to complete the entire installation.
What should happen
• The carpet displays a 1-foot pattern repeat in the width of the 12-foot breadth.
• This equals 12 full patterns, with ample selvage to trim the carpet for a clean-cut seam.
What may happen in the real world
• The carpet arrives 11 feet 11 inches in width from selvage to selvage.
• The installer must allow for the loss of one pattern.
• The seam is placed at 11 feet.
• The carpet breadth is measured net in the 12-foot width.
• There is not enough selvage to allow for a clean-cut seam, although the carpet displays 12 full pattern repeats.
Selvage edges must be cut from tufted products to construct an acceptable seam. However, some woven carpets, such as Axminster and Wilton, do not require cutting of the selvage edges.
If the width of the carpet is 12 feet 2 inches with a one-foot pattern repeat, one inch of selvage should remain on each edge to properly trim for seaming.
Example of a pattern count that may not work:
• If the carpet displays an 18-inch pattern repeat, it should measure12 feet (144 inches) across the width with allowance for trimming the selvage edge.
1. Received merchandise = 12 feet 13/4 inches or 145.75 inches across the width.
2. The exact pattern measures 18 1/4 inches.
3. Using this figure, carpet width requires 12 feet 2 inches or 146 inches.
4. This indicates that the final pattern is 1/4-inch short.
5. This does not allow for a full pattern repeat or trimming of the selvage.
6. It is necessary to cut the short pattern off the width to achieve a match with this example.
NOTE: The remaining carpet measures 10 feet 7 3/4 inches or 127 3/4 inches.
Every breadth will be this size; resulting in a shortage of carpet to complete the job for acceptance by the client.
It is the goal of both the manufacturer and the installation contractor that the pattern count meets the manufacturing specifications.
A full pattern count that utilizes the full breadth of carpet with a selvage edge, allowing for trimming, contributes to a successful installation.
VERY IMPORTANT INFORMATION:
If any of the following examples occur, it is NOT the installer's fault when the customer is not satisfied.
1. Short widths of patterned carpets created during manu facturing will result in problems for the installation contractor.
2. It is also critical that the person responsible for measuring a patterned carpet understand patterned carpet installation. If the carpet is measured short or the estimator does not allow sufficient yardage to install the carpet correctly, it is a FACT that the customer WILL NOT be satisfied. Patterned carpets CANNOT be installed as patchwork quilts. MEASURE for sufficient yardage!
3. The salesperson must understand patterns and realize if the selected carpet is suitable for the area and then SELL sufficient yardage!
4. The person responsible for cutting the patterned carpet for installation must cut it correctly.
The installation of patterned carpets requires a PARTNERSHIP. Once again, if it does not start RIGHT, it will NOT finish RIGHT.
