Claims
- 1. A method of unitizing a load of successive multi-unit layers with the layers stacked to form an array extending in a longitudinal direction with junctions extending in a lateral direction between the successive layers, comprising:
- dispensing a web from a web dispenser and stretching the web along the direction in which it is dispensed;
- collapsing the web into a configuration having roped edges of collapsed web material and a central unroped portion of web material connecting the roped edges;
- successively aligning the web with selected junctions by moving the web dispenser generally in the longitudinal direction relative to the load and stopping the relative longitudinal movement of the web dispenser and the load at times when the web is in alignment with one of the selected junctions; and
- successively wrapping the collapsed web around the load at each of the selected junctions, covering each of the selected junctions with the unroped central portion of the web and grabbing the successive layers with the roped edges to hold the successive layers together and to hold the units of the layers together.
- 2. A method of unitizing a load of successive units stacked in a longitudinal direction with junctions extending in a lateral direction between the successive units, comprising:
- dispensing a web and stretching the web along the direction in which it is dispensed;
- holding a leading end portion of the web adjacent the load;
- collapsing the web into a configuration having roped edges of concentrated web material and a central unroped portion of web of material connecting the roped edges;
- successively aligning the web with selected junctions by moving the web dispenser generally in the longitudinal direction relative to the load and stopping the relative longitudinal movement of the web dispenser and the load at times when the web is in alignment with one of the selected junctions; and
- successively wrapping the collapsed web around the load at each of the selected junctions, covering each of the selected junctions with the unroped central portion of the web, and grabbing the successive units with the roped edges to hold the successive units together.
- 3. A method of unitizing a load of successive multi-unit layers with the layers stacked to form an array extending in a longitudinal direction with junctions extending in a lateral direction between the successive layers, comprising:
- dispensing a web from a web dispenser and stretching the web along the direction in which it is dispensed;
- holding a leading end portion of the web adjacent the load;
- collapsing the web into a configuration having roped edges of collapsed web material and a central unroped portion of web material connecting the roped edges;
- aligning the web with one of the junctions; and
- wrapping the collapsed web around the load at the junction, covering the junction with the unroped central portion of the web, and grabbing the successive layers with the roped edges to hold the successive layers together and to hold the units of each layer together.
- 4. A method of unitizing a load of successive units stacked in a longitudinal direction with junctions extending in a lateral direction between the successive units, comprising:
- dispensing a web and stretching the web along the direction in which it is dispensed;
- holding a leading end portion of the web adjacent the load;
- collapsing the web into a configuration having roped edges of concentrated web material and a central unroped portion of web material connecting the roped edges;
- aligning the web with one of the junctions; and
- wrapping the collapsed web around the load at the junction, covering the junction with the unroped central portion of the web, and grabbing the successive units with the roped edges to hold the successive units together.
- 5. An apparatus for unitizing a load of successive multi-unit layers with the layers stacked to form an array extending in a longitudinal direction with junctions extending in a lateral direction between the successive layers, comprising:
- means for dispensing a web from a web dispenser and stretching the web along the direction in which it is dispensed;
- means for collapsing the web into a configuration having roped edges of collapsed web material and a central unroped portion of web of material connecting the roped edges;
- means for successively aligning the web with selected junctions by moving the web dispenser means generally in the longitudinal direction relative to the load and stopping relative longitudinal movement of the web dispenser and the load at times when the web is in alignment with one of the selected junctions; and
- means for successively wrapping the collapsed web around the load at each of the selected junctions, to cover each of the selected junctions with the unroped central portion of the web, and grap the successive layers with the roped edges to hold the successive layers together and to hold the units of the layers together.
- 6. An apparatus for unitizing a load of successive units stacked in a longitudinal direction with junctions extending in a lateral direction between the successive units, comprising:
- means for dispensing a web and for stretching the web along the direction in which it is dispensed;
- means for collapsing the web into a configuration having roped edges of concentrated web material and a central unroped portion of web material connecting the roped edges;
- means for successively aligning the web with selected junctions by moving the web dispenser means general in the longitudinal direction relative to the load and stopping the relative longitudinal movement of the web dispenser and the load at times when the web is in alignment with one of the selected junctions; and
- means for successively wrapping the collapsed web around the load at each of the selected junctions, to cover each of the selected junctions with the unroped central portion of the web, and grab the successive units with the roped edges to hold the successive units togethers.
- 7. An apparatus for unitizing a load of successive multi-unit layers with the layers stacked to form an array extending in a longitudinal direction with junctions extending in a lateral direction between the successive layers, comprising:
- means for dispensing a web from a web dispenser and stretching the web along the direction in which it is dispensed;
- means for collapsing the web into a configuration having roped edges of collapsed web material and a central unroped portion of web of material connecting the roped edges;
- means for aligning the web with one of the junctions; and
- means for wrapping the collapsed web around the load at the junction, to cover the junction with the unroped central portion of the web, and grab the successive layers with the roped edges to hold the successive layers together and to hold the units of each layer together.
- 8. An apparatus for unitizing a load of successive units stacked in a longitudinal direction with junctions extending in a lateral direction between the successive units, comprising:
- means for dispensing a web and for stretching the web along the direction in which it is dispensed;
- means for collapsing the web into a configuration having roped edges of concentrated web material and a central unroped portion of web material connection the roped edges;
- means for aligning the web with one of the junctions and
- means for wrapping the collapsed web around the load at the junction, to cover the junction with the unroped central portion of the web, and grab the successive units with the roped edges to hold the successive units together.
