Abstract
A bias tape maker comprises a thin walled outer member and an inner core member fitted in the outer member. The outer member includes a bottom wall, a pair of side walls extending upright from the bottom wall, and a pair of roof margins bent toward each other. Further, the outer member has a tape entry opening and a tape exit slit. The inner core member has a pair of longitudinal grooves for receiving the pair of roof margins. A tape guide passage is formed between the outer member and the inner member to extend from the tape entry opening of the outer member to the tape exit slit. The tape guide passage includes a tape folding portion adjoining the tape exit opening. The bottom wall of the outer member is formed with a tape advancing slot extending longitudinally between the tape entry opening and the tape exit slit.

A bias tape maker comprising:
- a thin walled outer member including a bottom wall, a pair of side walls extending upright from the bottom wall, and a pair of roof margins bent toward each other, the outer member having a tape entry opening and a tape exit slit, the outer member being tapered from the tape entry opening to the tape exit slit;
- and
- an inner core member fitted in the outer member and having a pair of longitudinal grooves for receiving the pair of roof margins;
- wherein a tape guide passage is formed between the outer member and the inner member to extend from the tape entry opening of the outer member to the tape exit slit, the tape guide passage including a tape folding portion adjoining the tape exit opening;
- wherein the bottom wall of the outer member is formed with a tape advancing slot extending longitudinally between the tape entry opening and the tape exit slit;
- wherein the inner core member has a larger width portion immediately below the pair of longitudinal grooves, and a smaller width portion immediately below the larger width portion;
- and
- wherein the larger width portion provides a pair of downwardly facing steps each of which extends generally in parallel to a bottom surface of the inner member.
A bias tape maker comprising:
- a thin walled outer member including a bottom wall, a pair of side walls extending upright form the bottom wall, and a pair of roof margins bent toward each other, the outer member having a tape entry opening and a tape exit slit;
- and
- an inner core member fitted in the outer member and having a pair of longitudinal grooves for receiving the pair of roof margins;
