Patent ID: 7241255

Claim:
A method for attaching a pair of corresponding hook-and-loop fasteners on a carton including a carton body and an openable and closeable lid, each of the pair of hook-and-loop fasteners having an adhesive back surface and an engaging front surface adapted to engage with each other to maintain a closure state of the lid relative to the carton body, the method comprising: a) preparing a first band-shaped exfoliation sheet on which a plurality of first hook-and-loop fasteners spaced apart at a first distance are attached via the adhesive back surfaces thereof; b) preparing a second band-shaped exfoliation sheet on which a plurality of second hook-and-loop fasteners spaced apart at a second distance and engageable with and disengageable from the first hook-and-loop fasteners are attached via the adhesive back surfaces of the second hook-and-loop fasteners; c) feeding the first and second exfoliation sheets with the engaging front surfaces of the first hook-and-loop fasteners on the first exfoliation sheet oppositely disposed to the engaging front surfaces of the second hook-and-loop fasteners on the second exfoliation sheet; d) bending the first exfoliation sheet in a knife-edged shape toward a back surface side thereof at a first downstream end of a feeding direction of the first exfoliation sheet to exfoliate the first hook-and-loop fasteners from the first exfoliation sheet at the first downstream end thereof, and engaging the exfoliated first, hook-and-loop fastener with the corresponding second hook-and-loop fastener on the second exfoliation sheet through the engaging front surfaces of the first and second hook-and-loop fasteners; e) bending the second exfoliation sheet in a second knife-edged shape toward a back surface side thereof at a second downstream end of a feeding direction of the second exfoliation sheet, which is further downstream than the first downstream end of the feeding direction of the first exfoliation sheet, to exfoliate the first and second hook-and-loop fasteners from the second exfoliation sheet at the second downstream end thereof, and attaching the exfoliated first and second hook-and-loop fasteners through the adhesive back surface of the second hook-and-loop fastener on a front surface of the carton body or a back surface of the lid of the carton in an open state of the lid relative to the carton body; and f) closing the lid of the carton so that the adhesive back surface of the first hook-and-loop fastener can be attached on the back surface of the lid or the front surface of the carton body.
