Method of and apparatus for forming trim cover

A method of forming trim cover, comprising the steps of;

• a. feeding an assembly of a sheet of covering material and wadding material, with the covering material side of said assembly facing upward, onto support means for receiving and supporting said assembly thereon, said support means being provided with at least one straight slit-like hole;
• b. pressing downwardly a portion of said assembly substantially positionally corresponding to said at least one straight slit-like hole of said support means to cause the same portion of said assembly to be dented and a portion of said wadding material of said assembly positionally corresponding to said at least one straight slit-like hole of said support means to be protruded downwardly from said support means through said at least one straight slit-like hole of said support means;
