ABSTRACT:
A mop head is made from a molded polymer carrier in the form of a channel with inturned lips or barbs on opposed flanges that retain compressed mop material, such as a block of sponge for a sponge mop. Glue is not required, and assembly does not require deformation of a malleable carrier material to squeeze inwardly on the sponge or the like. The lips of the flanges of the preformed molded channel are inwardly inclined toward one another and rearward in the channel, forming an entrant section leading into a nip. The lips hook into the sides of the block of mop material as compressed. Proceeding outwardly from the nip, the entrant section holds the mop material is a progressively more expanded state. The method of assembly includes compressing a block of mop material between two surfaces to reduce its thickness and to stiffen it, and then driving the compressed mop material into the channel, whereupon expansion of the mop material engages the lips or barbs. The molded polymer carrier channel is relatively rigid and can have reinforcements to resist resilient opening of the channel. The extent of compression of the mop material is substantial, for example, by a factor of four or five during compression, and another factor of two when passing through the nip between the lips.
