Strip Web Options and Results
Define a carrier web type and place it in the strip layout.
Carrier Web definition is a critical step in the strip layout process when creating the sketch for the carrier. It will be a contributing factor to the blank orientation, overall material consumption, and blank stability during the strip progression process.
Webs commonly have two different types of attachments.
-
Carrier to Blank - A web attaches the blank being formed to the steel coil or strip.
-
Blank to Blank – A web attaches the blanks together to stabilize the progression movement process ('Part to Part').
The web attachment selection is based on a variety of criteria and functions, such as the need for extra pilots, stabilizing blank/part during the progression movement (minimizing bounce), predicted blank pull in during forming, and ease of trimming.
Carrier Webs can also be put into two general types, fixed or stretch.
-
Fixed webs form a rigid connection between its attachment points.
-
Stretch webs form a flexible connection between its attachment points.
Note: This function is enabled only when the strip design environment is activated.
