Device for attaching the leading end of a roll of paper web

摘要

The leading end (6) and the second layer (9) of the spare paper roll (1) are connected to each other by drops (8) of a material (15), which solidifies at room temperature. Each drop is located in part on the front end of a first layer (2), and on the second layer. Several drops form a thread (8). A strip (7) of active adhesive material is applied to the front end of the first paper layer. The part of the thread of drops on the first paper layer, is located at least partially on the adhesive strip. The front end is retained on the second layer by fibrous threads.
