A pad (10) comprising a plurality of flexible sheets (11) in a stack, and padding means for releasably adhering parts of the major surfaces of adjacent sheets in the stack together to maintain the sheets in the stack. That padding means is provided in that at least some of said sheets having patterns of coadhesive (18a, 18b) coated on their major surfaces, which patterns of coadhesive are adhered to patterns of coadhesive on adjacent sheets in the stack and releasably adhere parts of the major surfaces of adjacent sheets (11) in the stack together in surface to surface relationship until the patterns of coadhesive (18a, 18b) are peeled apart.
L'invention a trait à un bloc-notes (10) comprenant plusieurs feuilles souples (11) constituant une pile ainsi que des bandes adhésives permettant de faire adhérer, tout en les laissant détachables, des parties des surfaces principales de feuilles contiguës dans la pile et ce, afin de maintenir les feuilles empilées. Certaines, au moins, desdites feuilles possédant des zones enduites de co-adhésif (18a, 18b) sur leur surface principale, comportent ces bandes adhésives. On fait adhérer ces zones enduites de co-adhésif à d'autres zones identiques se trouvant sur des feuilles contiguës dans la pile. Ces parties des surfaces principales des feuilles contiguës (11) dans la pile, qui adhèrent, tout en restant détachables, les unes aux autres, restent en relation surface contre surface jusqu'à ce que soient séparées les zones porteuses de co-adhésif (18a, 18b).
