Abstract
The current invention concerns an improved method for intermittently providing strips of a continuous first web material onto a continuous second web material, in particular a method for manufacturing tampon blanks, in a continuous process, thus avoiding the disadvantages of stop-and-go methods. Furthermore, an apparatus or system is provided for executing said methods.
Claims10
Method for manufacturing tampon laminate, comprising the steps of:
- a. supplying a continuous first web material at a first speed, whereby said first speed is greater than zero;
- b. cutting strips of the continuous first web material, whereby the strips are cut transversally with respect to a longitudinal axis of the continuous first web material and equidistantially repeated over the longitudinal axis of the continuous first web material;
- c. supplying a continuous second web material at a second speed, which is higher than the first speed;
- d. accelerating the strips from the first speed to the second speed;
- e. bonding at least parts of the strips of the first web material to the continuous second web material, thereby forming a laminate structure;
- characterized in that the step of accelerating the strips from the first speed to the second speed is conducted essentially concurrently with the step of bonding at least parts of the strips of the first web material to the continuous second web material, thereby forming a laminate structure, and in that the step of accelerating the strips is conducted essentially concurrently with the step of cutting strips of the continuous web material.

Method for intermittently providing strips of a continuous first web material onto a continuous second web material, comprising the following steps:
- a. supplying the continuous first web material at a first speed, whereby said first speed is higher than zero;
- b. cutting strips of the continuous first web material, whereby the strips are cut transversally with respect to a longitudinal axis of the continuous first web material;
- c. supplying a continuous second web material at a different second speed, whereby the second speed is higher than the first speed;
- d. accelerating the strips from the first speed to the second speed;
- e. bonding at least parts of the strips to the continuous second web material;
- characterized in that the step of accelerating one of the strips from the first speed to the second speed is conducted essentially concurrently with the step of bonding at least parts of said one of the strips to the continuous second web material and essentially concurrently with the step of cutting said one of the strips of the continuous web material.
