Latest Patents

One of Gerd Nohl's latest patents is a device for determining the angular position of the drive shaft in a position indicating device, particularly for industrial sewing machines. This device features a slotted wheel and a first track of slots that allows for null-point synchronization over a small range of rotational angles. It establishes definite angular positions using a second track with slots of various widths. The first track is associated with two light barrier arrangements, while the second track is linked to one light barrier arrangement. Evaluating systems connected to the receivers determine the rotary angle position based on the number of slots and the size of the slots passing through.

Another significant patent is for an electric motor drive for a sewing machine. This drive is designed to improve the dynamic performance of the sewing machine by allowing the needle to be reciprocated between upper and lower end positions. The drive is in direct connection with the main shaft and can be controlled at variable speeds through a control system. It includes an input switch for command pulses that trigger defined movements of the drive and main shaft.
