Claims14
An apparatus for forming a hem, comprising:
- a horizontal surface for supporting a surface of a banner;
- a linear edge positioned on said horizontal surface;
- a prefolder for applying a prefold to a banner, the prefolder offset from the linear edge at an angle of between 0.25° to 5°, the prefolder further defining an upper edge defining an angle from 2° to 10° relative to the horizontal surface and an entrance of the prefolder positioned closer to the linear edge than an exit of the prefolder;
- a tape station for use in application of tape to a banner;
- a hemmer for use in folding the banner, the hemmer offset from the linear edge at an angle of between 0.25° to 5°, the hemmer further defining an upper edge defining an angle from 2° to 10° relative to the horizontal surface and an entrance of said hemmer positioned closer to the linear edge than an exit of the hemmer;
- a driving roller for use in moving the banner and for use in compressing the banner and the tape to form a hem said driver roller having an axis of revolution perpendicular to said linear edge;
- and
- wherein when a banner is fed through the apparatus, the tape and the formed hem are positioned to correctly align and maintain a straight line relative to each other.
