Abstract
A device for processing sheets, rolls or the like, preferably sheets or rolls of corrugated paper, into useful articles. More specifically, the invention relates to a paper wrapping device that can convert a sheet or strip of paper into a useful article comprising a plurality of wrapped paper layers, suitable for use as a support member or a pallet stringer. Also the invention provides a device that contains a conveying unit which transfers a material, such as paper, to a forming unit which produces a core layer and further wraps additional layers in a clockwise or counterclockwise direction around said core in one or more layers to form a support member having a solid wrap of continuous layers.
Claims46
A paper wrapping device for producing an elongated support member having a plurality of wrapped layers, comprising:
- a conveying unit adapted to receive paper from a paper source, the conveying unit comprising a feed controller that controls orientation of paper received from the paper source utilizing a sensor, and adjusts the orientation if the sensor determines the paper is out of alignment;
- and
- a forming unit located downstream from the conveying unit and operatively receiving paper from the conveying unit for winding the paper into a support member, the forming unit comprising a first winding arm, a second winding arm, and a clamp assembly, each rotatable about an axis of rotation, the clamp assembly including a clamp movable in relation to and engagable with one of the winding arms to hold a portion of the paper between the clamp and the winding arm during at least a portion of the winding process.
A paper wrapping device for producing an elongated support member having a plurality of wrapped layers, comprising:
- a forming unit comprising a motor having a rotatable shaft, wherein a length adjustment member is connected to the rotatable shaft, wherein a first winding arm is connected to the length adjustment member and a second winding arm is connected to the rotatable shaft or the length adjustment member, wherein the first and second winding arms are rotatable about a rotational axis and adapted to wind paper from a paper source into a support member having one or more wrapped layers, wherein the forming unit further comprises a clamp assembly including a clamp operatively movable in relation to and engagable with one of the winding arms to hold a portion of the paper between the clamp and the winding arm during at least a portion of rotation of the winding arms, and wherein the forming unit motor is connected to a winding arm carriage and is movable substantially laterally with respect to a feed direction of the paper and capable of separating contact between the support member and the winding arms after a support member has been formed.
A paper wrapping device for producing an elongated support member having a plurality of wrapped layers, comprising:
- a conveying unit adapted to receive paper from a paper source, the conveying unit comprising a feed controller that controls orientation of paper received from the paper source utilizing a sensor, and adjusts the orientation if the sensor determines the paper is out of alignment;
- and
- a forming unit located downstream from the conveying unit and operatively receiving paper from the conveying unit for winding the paper into a support member, the forming unit comprising a first winding arm, a second winding arm, and a clamp assembly, each rotatable about an axis of rotation, the clamp assembly including a clamp movable in relation to and engagable with one of the winding arms to hold a portion of the paper between the clamp and the winding arm during at least a portion of the winding process, and wherein the conveying unit includes at least three tension members disposed adjacent a guide roller for selectively applying pressure to one or more portions of the paper between one or more of the tension members and the guide roller in order to control orientation of the paper.
A paper wrapping device for producing an elongated support member having a plurality of wrapped layers, comprising:
- a forming unit comprising a motor having a rotatable shaft, wherein a length adjustment member is connected to the rotatable shaft, wherein a first winding arm is connected to the length adjustment member and a second winding arm is connected to the rotatable shaft or the length adjustment member, wherein the first and second winding arms are rotatable about a rotational axis and adapted to wind paper from a paper source into a support member having one or more wrapped layers, wherein the forming unit further comprises a clamp assembly including a clamp operatively movable in relation to and engagable with one of the winding arms to hold a portion of the paper between the clamp and the winding arm during at least a portion of rotation of the winding arms, wherein the forming unit motor is connected to a winding arm carriage and is movable substantially laterally with respect to a feed direction of the paper and capable of separating contact between the support member and the winding arms after a support member has been formed, wherein the wrapping device further includes a bonding agent application device adapted to selectively apply an adhesive to the paper, and wherein the bonding agent application device is located downstream from the conveying unit and upstream from the forming unit.
