Abstract
A centerflow rolled wiper system for a coreless rolled web which obviated dispensing problems caused by roping of the web during dispensing while simultaneously achieving significant space saving advantages. The coreless rolled web includes a plurality of wipers defined by lines of perforation across the width of the web, each of said wipers having a length L. The initial center hole of the roll has a cross-sectional perimetric dimension which is less than two times L, the roll having been bi-directionally compressed to a generally rectangular cross section. There is a dispenser carton in which the bi-directionally compressed roll resides, the dispenser carton sized to maintain said generally rectangular cross section of the bi-directionally compressed rolled web. A dispensing port through at least one end of the dispenser carton allows a user to withdraw the wipers from the center of the coreless roll.
