Web-wound rolls with a web edge treatment with microspheres and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more stripes of coated material are disposed adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the one or more stripes of coated material.

A reservoir assembly (40) comprises a container (4), a support assembly (42) on which the container (4) is mounted and fixed and a rotary electric vibrator device (44) coupled to the support assembly (42). The container holds a shear thinning additive for a plastics material. The reservoir assembly is arranged so that on operation of the device (44), an appropriate frequency and amplitude of vibration is applied to the container (4) and, therefore, its contents. As a result, a liquid dispersion in the container is shear thinned and recovery of dispersion from the container is increased.
