Abstract

The wire card napping machine has at least one driven cylinder, with several pick-up devices, each of which is equipped with at least one napping roller of a different roller type and is embedded in the side disks of the cylinder, it being possible to rotate at least one pick-up device by means of an adjusting device. The adjusting device has a lifting device, which can be operated in a controlled manner and to which a segment bearer, which can be moved by the lifting device between a starting position and an operating position, which brings about a pick-up device that is to be rotated in a defined angle, is connected in hinged fashion and the segment bearer lies in its operating position against a wheel, which is disposed firmly at the pick-up device that is to be rotated. The adjusting device has assigned to it an unlocking device, which has a further lifting device, which can be operated in a controlled manner, to which an unlocking segment, which can be moved by the further lifting device between a starting position and an operating position, which brings about the unlocking of the pick-up device that is to be rotated through a defined angle, is connected in hinged fashion. The unlocking segment, in its operating position, is connected in hinged fashion to a locking device, which is disposed at a pick-up device that is to be rotated, before the pick-up device in question is rotated to bring about the unlocking.

A wire card napping machine for fabrics comprising:

at least one driven cylinder rotatably supported in a machine frame and having first and second side disks;
pick-up devices supported by said first and second side disks;
each of said pick-up devices having at least one napping roller of a first type;
at least one of said pick-up devices having a napping roller of a second type in addition to a napping roller of said first type;
said one pick-up device including means for rotatably supporting said one pick-up device on said first and second side disks;
an adjusting device having a first lifting device, a segment bearer movably supported by said first lifting device permitting transport of said segment bearer between a starting position and an operating position for engaging and rotating said one pick-up device through a defined angle;
a disk fixed to said one pick-up device and disposed to functionally engage said segment bearer, at said operating position, to effect rotation of said one pick-up device through said defined angle as said cylinder rotates;
said adjusting device having an unlocking device including a second lifting device;
an unlocking segment movably supported by the second lifting device to permit travel between a starting position and an operating position to effect unlocking of said one pick-up device for the purpose of said rotation through said defined angle;
and
said one pick-up device including a locking device for preventing rotation of said one pickup device;
said locking device having means for movably supporting said locking device to permit movement between a first position whereat said locking device prevents rotation of said one pick-up device and an operating position whereat said locking device permits rotation of said one pick-up device;
said locking device and said unlocking segment being engageably disposed when said unlocking segment is at said operating position thereof to effect displacement of said locking device to said operating position thereof as said cylinder rotates to accomplish unlocking prior to said rotation of said one pick-up device by said segment bearer;
and
means for controlling said first and second lifting devices.
