OPERATING SEQUENCE.
Use the correct Signode products for your application. If you need help contact your Signode
Representative. Before using this sealless tool, read the Operation and Safety Instructions
contained in this manual.
9.
JOINT FORMATION
Sealless joints are formed when overlapping straps are punched simultaneously creating
interlocking keys. However, the integrity of the joint is obtained when the keys punched in the
upper strap move in relation to the keys on the bottom strap, allowing the straps to interlock.
The movement necessary to create the interlock comes from the strap tension release where
the top strap moves one direction and the bottom strap moves in the other direction.
Therefore, never attempt to make a sealless joint without having the straps under tension.
This tool is a punch type sealer. A properly formed joint will appear as shown in the
illustration. If the joint does not appear as shown,
then the operator must proceed as follows:
A. Ensure that the tool's operating instructions are
being followed before applying another strap.
B. Ensure that tension has been applied to the
straps before the sealer handle is activated.
Tension is necessary to ensure that the keys fully interlock.
C. After confirming the above cut the strap off and apply another.
If the joint still does not appear as shown, then inspect the tool for worn and/or damaged
parts. Replace tool parts as needed. NEVER HANDLE OR SHIP ANY LOAD WITH
IMPROPERLY FORMED JOINTS. Misformed joints may not secure the load and could cause
serious injury.
Always tuck the strap end back into the dispenser when not in use.
10. CUTTING TENSIONED STRAP
Using claw hammers, crowbars, chisels, axes or similar tools can cause tensioned strap to fly
apart with hazardous force. Use only Signode cutters designed for cutting strap such as the
Model CU-30. Read the instructions in the cutter's manual for proper procedure in cutting
strap. Before using any Signode product read its Operation and Safety Manual.
