Herein are disclosed high loft spunbonded webs that are substantially free of crimped fibers and gap-formed fibers. The transport track includes transport driving devices that cause the carrier to travel and stop. Any change in position of the indicator body, which is caused by inflowing or outflowing pressure medium, can be monitored visually or through the use of sensors. Diagnostic, screening, and therapeutic methods utilizing compositions of the invention are also provided. When the locking plate is in the locking position, the lateral sides of the plate extend inside the rings and are engaged with corresponding notches in an upper internal rim of the lens-retaining collars.
