Abstract
A portable integral compact rug binding machine which may be guided along the outside edge of a carpet to be bound by means of a handle is disclosed. The rug binding machine is provided with a vertically mounted drive motor and a low or close to the floor base member wherein a portion or zone of the carpet being bound curves up and over the base plate or support means without need for folding the carpet back over its entire length. The binding machine performs the binding operation with the use of a single binding thread fed to the needle from above. A driven carrier roll is provided for moving the carpet with respect to the binding needle, and in one embodiment, an adjustable pressure roller is provided for enabling binding around curved edges of the carpeting.
Claims32
A binding machine for materials having an upper carpet surface and a lower basic surface such as carpets, carpet strips and the like, comprising:
- a machine frame provided with a drive motor;
- said motor driving a binding mechanism means including a substantially vertically guided straight needle;
- said binding mechanism being mounted on a base member or support means for lifting the region of the material to be bound with the material being maintained during binding in a position with the upper carpet surface up;
- said machine frame being provided with a holder for the supply of a single binding thread introduced via the straight needle from above;
- means for carrying the material to be bound through the binding mechanism means;
- said binding mechanism including a looping mechanism means for looping said single thread;
- said machine frame with said motor, said carrier means and said binding mechanism means forming an integral, compact, portable unit operable by means of at least one hand grip to guide the binding machine along the outside edge of the material to be bound;
- said support means for lifting the region of the edge of the material being bound being of a relatively low or flat to the floor configuration relative to the configuration of the machine frame, and being short in the direction in which the material is carried through the machine;
- said carrying means having roller means mounted on the edges of an upper portion of said support means for guiding the lower basic surface of the material to be bound which is partially arched up to the upper surface of said support means from the flat to the floor position during binding;
- and,
- runners mounted to the lower portion of said support means for enabling movement of said machine on a floor.

- said support means being attached on the bottom of said column-shaped portion of the machine frame, pointing into a first direction;
- said first holder for the supply of binding thread being mounted on the side of said column-shaped portion, and projecting from the bottom part of said column-shaped portion into a direction opposed to said first direction;
- said first holder holding said supply of binding thread parallel to and beside said column-shaped portion;
- and,
- a second holder for binding strip being arranged beneath said first holder for said binding thread.

A binding machine for materials such as carpets, carpet strips and the like, comprising:
- a machine frame provided with a drive motor;
- said motor driving a binding mechanism means including a substantially vertically guided straight needle;
- said binding mechanism being mounted on a base member or support means for lifting the region of the material to be bound;
- said machine frame being provided with a holder for the supply of a single binding thread introduced via the straight needle from above;
- means for carrying the material to be bound through the binding mechanism means;
- said binding mechanism including a looping mechanism means for looping said single thread;
- said binding mechanism including a gripper means for grasping a thread loop formed by said needle after said needle passes through the material, said gripper moving said loop around a guide means extending along and covering the edge of the material to be bound and placing said loop on the other side of the material in such a position that said needle pierces the loop during the next pass through the material;
- said gripper means mounted so as to swivel on a shaft slanted with respect to the binding direction, whereby said gripper means, viewed in the direction of motion of the material relative to the machine, is located behind said needle when gripping the thread loop and passes in front of said needle on the other side of said material;
- and
- said guide means ending closely behind the needle's position when viewed in said direction of motion.
