Failing to secure the bobbin correctly can result in loose or unevenly wound bobbins, negatively affecting stitch consistency. For example, improperly placing the bobbin might lead to it wobbling during winding, resulting in an uneven thread distribution which could subsequently cause tension problems during sewing.
-
Threading the Bobbin Winder
This stage requires guiding the thread from the spool pin, through the pre-tensioning guide, and finally attaching it to the bobbin. The manual details the specific threading path for the bobbin winder, which might differ from the upper threading path. This pre-tensioning mechanism ensures consistent thread tension on the bobbin. Incorrectly threading the bobbin winder could result in overly tight or loose bobbins, impacting stitch quality and potentially causing thread jams or breakage. An example might be threading the bobbin winder without engaging the pre-tensioning guide, which could lead to a loosely wound bobbin.
-
Winding the Bobbin
This step involves engaging the bobbin winder mechanism and running the machine at a slow speed until the bobbin is fully wound. The manual usually specifies the appropriate speed and direction for bobbin winding. Overfilling the bobbin can cause thread jams, while underfilling can lead to frequent interruptions during sewing. An example is winding the bobbin too quickly, which might result in uneven tension and an overfilled bobbin, ultimately leading to thread breakage during sewing.
-
Securing the Wound Bobbin
After winding is complete, the thread must be carefully trimmed and the bobbin removed from the winder. The manual might provide instructions on how to secure the wound thread to prevent unraveling before inserting the bobbin into the bobbin case. Improper handling of the wound bobbin can lead to tangled thread and wasted time. For instance, failing to secure the end of the wound thread might cause it to unravel and become tangled when inserting the bobbin into the case.
Understanding these distinct facets of bobbin winding, as detailed in the Sears Kenmore sewing machine manual for model 158, is crucial for optimal machine performance. Correct bobbin winding directly affects stitch quality and contributes to the smooth, uninterrupted operation of the machine. Mastering this process, as outlined in the manual, ensures consistent sewing results and minimizes potential problems related to thread tension and bobbin handling.
