Chlorine free
This designation does not refer to the paper itself or to its possible chlorine content. Instead, it refers to the bleaching process during fibre production. "Low chlorine" papers are those in which no chlorine gas is used during fibre bleaching. Pulp is described as being totally chlorine free (TCF) when no chlorine compounds, i.e. not even chlorine dioxide, are used for bleaching.
Chlorine
Chemical substance used to remove residual lignin after digesting of cellulose and suitable for bleaching. However, this process results in organic chlorine compounds that have a negative impact on the environment (incl. dioxins) and that are not easily degradable under natural conditions. As a rule, production is nowadays carried out without the use of chlorine.
Cross Cutter

Papers that are not to be sold in web form are trimmed to the correct size with cross cutters. The webs to be cut are hung on an unwinder stand in such a way that each roll can be braked individually. The continuous paper web is then cut into sheets by a rotating knife. The length of the sheets is adjusted by changing the speed at which the knife rotates. To ensure that sheets are stacked correctly in the lay boy at the high operating speeds which are usual today, our cross cutter functions with a sheet overlapping system. This utilises belts running at a lower speed so that the sheets are slowed down and layered like overlapping tiles as they leave the cutter. At the end, they are counted and stacked.
