Abstract
The padded frame of a seat being upholstered rests on a support placing the back of the seat in vertical alignment under a carriage mounted on guides establishing a vertical freedom of movement of the carriage. The carriage has a cluster of resilient cantilever arms extending downward, each of the arms having a follower at the lower end adapted to move along the contour of the seat back. The cover for the seat back is slipped inside-out over the cluster of arms, and relative movement of the carriage toward the seat installs the cover outside-out. Other resilient arms in the cluster are preferably mounted on the frame of the machine, with relative movement provided by moving the seat unit with respect to the frame.
Claims4
In combination with a seating unit having a surface to be covered, a machine for installing an upholstery cover, said machine comprising:
- a frame;
- a supporting structure, means for moveably mounting said supporting structure on said frame, said supporting structure having a receptacle adapted to receive said unit preparatory to receiving a cover over at least a part thereof;
- a carriage, means for moveably mounting said carriage mounted on said frame for movement parallel to the movement of said supporting structure;
- at least one cantilever arm mounted on said carriage, said arm having a longitudinal axis disposed parallel to said movement, said arm being resilient and providing biasing toward said unit surface said movement causing the outer extremity of said arm to follow closely over the surface of said upholstery unit part;
- and
- operating means for inducing said movement.
