Hand device for making a bias tape

A hand device for making a bias tape comprising:

• an outer tubular member made of metallic sheet material and having a substantially oval rear end opening and a slit-shaped front end opening;
• said outer tubular member being gradually reduced or tapered from its rear end toward its front end;
• said outer tubular member having a top opening of a substantially triangular shape defined by a vertex positioned near said front end and a pair of sides divergently extending from said vertex;
• an internal solid member made of synthetic resin material and being gradually reduced or tapered from its rear end toward its front end at its top side so as to be exposed out of said top opening;
• said platform having a pair of said walls engaged with said pair of sides, respectively;
• said outer tubular member and said internal solid member being assembled together by inserting the latter into the former;
• a tape-folding passage formed between an internal wall of said outer tubular member and an external wall of said internal solid member;
• and
• said passage having a substantially U-shaped configuration in cross section at its rear end and being gradually changed in its configuration so as to provide a substantially flat annular configuration in cross section at its front end.
