The invention provides a pressure-sensitive adhesive sheet capable of regularly coiling during heating and expanding. Long sides or short sides of the adhesive sheet are parallel to a wide side of a release film; the adhesive sheet is rectangular and has long folds and short folds which are designed at intervals; two long sides of the adhesive sheet are coiled inwards along the short sides in the process of heating and expanding at the temperature of 90-180 DEG C, so that part of expansion stress is released in cutting folds; directionality and regularity of coiling of an adhesive tape are extremely high; the adhesive tape is shaped as a coiling drum; the coiling degree is greater than the size of the short sides by 50%; the residual viscidity of the adhesive tape in the expansion process can be better adjusted so as to ensure that damage to the appearance of slurries caused by irregular coiling when positive and negative electrodes of lithium batteries are coated with the slurries and roasted is avoided; a die cutting process comprises synchronous continuous operations of pasting bottom films, pasting transition protection films, punching, removing waste and coiling; the degree of precision is high; the situations that the release film is punched, the adhesive sheet is lacked and the edges are irregularly cut are avoided.
