Abstract
A wrapping machine which includes an elevated platform with a pair of opposed clamping members adapted to hold a narrow workpiece being wrapped therebetween. Each clamping member includes a flat base and a pair of sides for holding a narrow workpiece between the clamping members, with each of the clamping members being rotatably mounted. One of the clamping members is coupled to the platform and the other of the clamping members is coupled to a vertically movable arm. A vertical support is provided to support the vertically movable arm, with a first drive mechanism rotatably driving one of the pair of clamping members, and a second drive mechanism for moving the movable arm relative to the support to position the pair of clamping members with respect to the workpiece being wrapped.
Claims15
A wrapping machine comprising:
- an elevated platform;
- a pair of opposed clamping members adapted to hold a thin workpiece being wrapped therebetween, each said clamping member including a substantially horizontal flat base and a pair of sides extending beyond said base to surround and engage the sides of said thin workpiece for centering and holding said thin workpiece between said clamping members, wherein each said pair of sides diverges from each other in a direction extending away from said horizontal base for centering said thin workpiece, and wherein said clamping members are rotatably mounted;
- one of said pair of clamping members coupled to said platform and configured to support said thin workpiece, and the other of said clamping members positioned vertically above said one clamping member and coupled to a vertically movable arm;
- a vertical support supporting said vertically movable arm.
- a first drive means rotatably driving one of said pair of clamping members;
- and
- a second drive means for moving said movable arm on said vertical support to position said pair of clamping members with respect to said thin workpiece.

- a vertical support supporting said vertically movable arm;
- a first drive means rotatably driving one of said pair of clamping members, wherein said first drive means includes a first motor and a drive belt operatively connecting said first motor to said clamping member which is coupled to said platform;
- and
- a second drive means for moving said movable arm on said vertical support to position said pair of clamping members with respect to said thin workpiece;
- wherein said first drive means further includes a tensioning spring between said first motor and said platform to maintain said drive belt in tension.

A method of wrapping a narrow workpiece using a wrapping machine including:
- an elevated platform;
- a pair of opposed clamping members adapted to hold a thin workpiece being wrapped therebetween, each said clamping member including a substantially horizontal flat base and a pair of diverging sides extending beyond said base for centering and holding said thin workpiece between said clamping members, wherein each said pair of sides diverges from each other in a direction extending away from said horizontal base for centering said thin workpiece, and wherein said clamping members are rotatably mounted;
- one of said pair of clamping members rotatably coupled to said platform configured to support said thin workpiece, and the other of said clamping members positioned vertically above said one clamping member and coupled to a vertically movable arm;
- a vertical support supporting said vertically movable arm;
- a first drive means rotatably driving one of said pair of clamping members;
- and
- a second drive mans for moving said movable arm on said support to position said pair of clamping members with respect to said thin workpiece;
- said method comprising the steps of:
- placing said thin workpiece on said one clamping member which is coupled to said platform, wherein said one clamping member supports said thin workpiece;
- driving said second drive means whereby said movable arm is moved closer to said platform and said thin workpiece is centered and held between said clamping members;
- driving said first drive means to rotate said clamping member and said thin workpiece;
- and
- wrapping said thin workpiece simultaneously with said driving of said first drive means.
