摘要： Cover folders for permanently binding a stack of paper sheets without the use of fasteners. The cover folder has a binder spline which contains a quick drying adhesive which is protected by a removable protective film. The film is removed just prior to use to expose the adhesive. The cover folder allows for quick permanent binding of the stack of paper sheets which are pressed into contact with the adhesive. In alternative embodiments the adhesive may be applied directly to the binder spline from a dispenser and the stack of sheets then inserted in the spline.
