Abstract
In general, the present invention is directed to a process for producing multi-ply tissue products from a single ply tissue web and the resulting multi-ply products, which have good softness and strength characteristics. The process of the present invention generally involves producing a first single ply tissue web and then splitting the web into two separate single ply tissue webs that can be converted into a multi-ply web. In certain preferred embodiments the single ply web may be manufactured such that when it is split into two separate webs the two webs are substantially identical.
Claims16
A method for manufacturing a multi-ply tissue product comprising the steps of:
- a. providing first and second vertically arranged rollers;
- b. forming a first multi-layered tissue web comprising first and second fibrous outer layers and a middle fibrous layer disposed there between;
- c. splitting the first multi-layered tissue web horizontally to form a second and a third multi-layered tissue web, wherein the second and the third multi-layered tissue webs each comprise two fibrous layers;
- d. threading the second multi-layered tissue web about the first roller and threading the third multi-layered tissue web about the second roller thereby forming a split angle ranging from 15 to 180 degrees between the second and third multi-layered tissue webs;
- and
- e. plying the second and third multi-layered tissue webs together to form a multi-ply tissue product.
A method for manufacturing a two ply tissue product comprising the steps of:
- a. providing an uncreped through-air dried tissue web comprising first and second fibrous outer layers and a middle fibrous layer disposed there between;
- b. splitting the uncreped through-air dried web horizontally to form a second and a third multi-layered tissue web, wherein the second and the third multi-layered tissue webs each comprise two layers;
- c. threading the second multi-layered tissue web about a first roller and threading the third multi-layered tissue web about a second roller thereby forming a split angle between the second and third multi-layered tissue webs;
- d. varying the split angle from 15 to 180 degrees by adjusting the position of the first and second rollers relative to one another;
- and
- e. plying the second and third multi-layered tissue webs together to form a two ply tissue product.
