Abstract

The invention discloses a hollow foam roller. The hollow foam roller comprises an outer wrapping layer and an inside lining layer. The outer wrapping layer is a hollow cylinder. The inside of the outer wrapping layer is provided with a groove, in which the inside lining layer is arranged. Massage protrusions are arranged on the surface of the outer wrapping layer in a staggered mode. The shape of the inside lining layer is a hollow cylinder with two ends opened. The wall thickness of the inside lining layer is the same as the depth of the groove. The hollow foam roller has following beneficial effects: the hollow foam roller is low in cost, few in procedures, short in manufacture period, and reasonable in machining method; without utilization of glue, the purpose of saving energy and protecting environment is fulfilled; and the produced foam roller has advantages of non-splicing surface material, uniform hardness, high strength of a pattern surface, no crack, bright and colorful external appearance of a product, high rate of resilience, durability and no deformation.
