Abstract
A fur sewing machine having a blower device connected with a source of compressed air which deflects the fur hairs of the material to be sewn during sewing. The connecting line between the source of the compressed air and the blower contains a heating device which heats the compressed air. A mechanism for controlling the air flow and the heater is also provided.
Claims10
A fur sewing machine with a blowing arrangement for deflecting the hairs of fur pieces from the area being sewn, which blowing arrangement comprises a blower device, a source of compressed air, a connecting line between the source of compressed air and the blower device for supplying compressed air to the blower device, the blower device being mounted on the sewing machine so as to enable discharge of the compressed air in a direction that deflects the hairs of the fur pieces in the area being sewn, a heating device disposed in the connecting line for heating the compressed air, the heating device including a pipe fitting, the pipe fitting having a pipe portion and fittings at each end thereof for engaging the connecting line so that compressed air may flow through the pipe fitting, a helical electric resistance heater disposed within the pipe fitting, which resistance heater is coaxial with the pipe fitting and extends between the ends thereof.
A fur sewing machine with a blowing arrangement for deflecting the hairs of fur pieces from the area being sewn, which blowing arrangement comprises a blower device, a source of compressed air, a connecting line betwen the source of compressed air and the blower device for supplying compressed air to the blower device, the blower device being mounted on the sewing machine so as to enable discharge of the compressed air in a direction that deflects the hairs of the fur pieces in the area being sewn, the blower device including a blow tube defining an exit nozzle for the compressed air, the blower device being movable so as to selectively direct the blow tube towards the area being sewn when in an operating position or away from the area being sewn when in a rest position, a heating device disposed in the connecting line for heating the compressed air, control means for causing the heating device and the source of compressed air to be activated when the blower device is in the operating position and causing the heating device and source of compressed air to be deactivated when the blower device is in the rest position.
