Abstract
Spindles and cover assemblies for dispensing sheet product for use with coreless sheet product rolls. The spindle may include a hollow cylindrical body, which may have an elongated channel in a sidewall; a rod which extends partially out of the body; and a spring disposed within the body in biasing contact with the rod. The rod may include a flexible tab matingly engaged within the channel, permitting the rod to translate within the hollow cylindrical body without falling out. The hollow cylindrical body may have an end with an opening bounded by an inward facing ledge, and the rod may include a radial ledge, such that the rod can translate within the body but cannot fall out due to interference between the inward facing ledge and the radial ledge. The spindle may include a friction hub disposed about and rotatable around the hollow cylindrical body between ends of the body.
