Abstract (en)
The present invention relates to a closing sheet for wound products created from a recycled paper support with a hydrophobic varnish for preventing the curving caused by the short fibres of the recycled paper from which the support is made. The manufacturing method that allows obtaining said sheet involves a continuous execution of the longitudinal cutting of the original roll, along the width of the sheet, and placing the tearing strip without rewinding between said two steps. The present invention also defines the machine that executes the aforementioned method.
