Abstract
A method and apparatus for sealing a tail of a log of web material is provided. A linear tail seal system includes a track and electromagnets that cooperate to move a linear motor. The tail of the log is detected by an electronic eye as the log moves near the linear tail seal system, which signals an adhesive applicator to apply an adhesive to the log. An ironing roll forms a tail seal by adhesively ironing the tail seal on the log. A process for making a roll having a well defined handle formed by the linear tail seal system is also provided.
Claims13
A roll with a handle configured to be grasped for initial use of the roll, the handle having a length which falls within a middle 80% of a target length from between 90% to about 98% of the time, the roll made by the process comprising the steps of:
- a) providing a linear tail seal system disposed proximate a winder configured for forming a log of web material, the linear tail system having an adhesive applicator, a magnet and a track disposed transverse to the log;
- b) rotating the log such that a tail of the log depends in a direction of the linear tail seal system;
- c) propelling the adhesive applicator linearly along the track via the magnet to traverse the log to apply an adhesive;
- and
- d) spraying the adhesive from the adhesive applicator to form a tail seal on the log as the adhesive applicator linearly traverses the log.
A plurality of roll products with handles configured to be grasped by consumers, each handle of each of the roll products defining a standard deviation of between 0% to about 20% from a target handle length.
