Abstract

A calender for paper or paperboard is sold together with a guarantee and preventative maintenance plan. The sales plan incorporates a warranty period of 3 to 5 years with a scheduled maintenance plan which is performed or overseen by the supplier of the calender. The scheduled maintenance is related to the warranty such that if the scheduled maintenance is not performed, the warranty is voided. The scheduled maintenance also allows the calender supplier to monitor the use of the calender and to inform the purchaser when it is evident that the calender is being misused. This method of sale of a calender and calender warranty minimizes unscheduled maintenance, and damage through improper operation.

Claims

1. A method of selling a papermaking or boardmaking calender comprising the steps of:

selling a calender and a calender warranty of three or more years, at a selected price;

performing scheduled preventative maintenance on the calender sold, according to a scheduled maintenance plan commensurate with the length of the calender warranty, the maintenance being performed according to the maintenance plan, and under the control of the entity selling the calender;

wherein rights under the warranty are dependent upon the the scheduled maintenance being performed according to the scheduled maintenance plan, and under the control of the entity selling the calender.

2. The method of claim 1 wherein the scheduled preventative maintenance is scheduled to occur after the machine has operated for a selected number of hours.

3. The method of claim 1 wherein the scheduled preventative maintenance is scheduled to occur after a selected passage of time.

4. Wherein the selected price includes charges associated with the performance of the preventative maintenance, but wherein a purchaser is not required to pay those portions of the selected price associated with the performance of preventative maintenance until such time as the preventative maintenance is actually performed.
