Needle Replacement for the Newlong NP-7A Portable Bag Closer

by Lori Ross

When to Replace the Needle in the Newlong NP-7A Portable Bag Closer?

Broken needle, bent needle, dull needle – replace it!

 

You have a bag full of product and have stitched it closed with the Newlong NP-7A. The filled bag is tossed onto the pallet and the stitches come undone. Product falls out and you are left with a mess. What happened? It’s possible that the needle in your NP-7A bag closer simply needs to be replaced.

 

Obviously if you have broken the needle, it must be replaced. Broken needles happen by hitting a dried bean, corn kernel or piece of coal while stitching the bag closed. Hitting the product doesn’t always break the needle – sometimes it may just bend the needle.

 

The DNx1 # 25 / B01002 standard needle generates an incredible amount of heat while closing the bags. With enough heat, the needle may warp. The B01002 needle may not look bent, but even a slight bend can be enough to cause the stitches to unravel.

 

Forcing the bag thru the Newlong NP-7A can also bend the needle. Pulling a jammed bag out of the bag closer can also cause a problem.

 

If your closed bags are unraveling, you can send the NP-7A in to Tracey Packaging, Inc. for service. But if you want to save a few dollars, first try replacing the needle.

 

When replacing the needle, make sure you have the correct style and size needle. There are a lot of different bag closing machines available and many of them require different needles. The D5 needle for the Fischbein portable bag closer will fit into the Newlong NP-7A bag closer, but the Fischbein needle is shorter than the DNx1 # 25 / B01002 needle and the stitch will not loop correctly.

 

The Newlong NP-7A needle will fit in backwards, but will result in stitches unraveling. Needles have a “scarf” – an indentation near the eye of the needle. To correctly replace the needle, this concave part should be facing the looper.

 

Needles are relatively inexpensive and replacing the needle can be an easy fix to a big stitch unraveling problem. For help choosing the right needles for your bag closing equipment, contact Tracey Packaging, Inc. today.
