Abstract
An embroidery system including an embroidery frame assembly having an inner first frame (51) and an outer second frame (53), a portion of a planar formation to be processed being able to be clamped therebetween. The first frame (51) is connected by a bridge (61) to a radially outer secondary connector (57), and a connecting portion (63) of this bridge (61) bridges the second frame (53) when the latter is connected to the first frame (51). When combined with an embroidery module connected to a free arm sewing machine, the embroidery frame assembly enables in a simple manner the embroidering of pouch-type and tubular planar formations.
Claims14
An embroidery system, comprising:
- a sewing machine (10) having a lower arm (17) which protrudes laterally from a machine stand (11), an upper side of said lower arm (17) defining a sewing plane;
- an embroidery module (30) and an embroidery frame (50), the embroidery module (30) comprises:
- a first support (31) on which a primary connector (37) is mounted so as to be movable in a second displacement direction (P2) parallel to the sewing plane,
- said first support (31) is disposed opposite the machine stand (11) or laterally next to the lower arm (17) and is mounted so as to be movable in a first displacement direction (P1) parallel to the sewing plane;
- the embroidery frame (50) comprises:
- a first frame (51) and a second frame (53),
- a device for at least one of clamping or holding a portion of a planar formation (1) to be processed between the first and second frames (51, 53),
- the first frame (51) is adapted to be disposed on an upper side and the second frame (53) is adapted to be disposed on a lower side of the planar formation (1),
- a secondary connector (57), which is releasably connectable to the primary connector (37) of the embroidery module (30), disposed outside the first frame (51), so as to be radially spaced apart from the first frame, and is rigidly connected to the first frame (51) by a bridge (61),
- wherein the bridge (61) comprises at least one connecting portion (63) which connects the first frame (51) to the secondary connector (57) and bridges the second frame (53) when the second frame is connected to the first frame (51), and wherein a spacing (L4), or a height of a void defined between the connecting portion (63) and the second frame (53) is from 1 centimeter to 10 centimeters.
An embroidery frame assembly of an embroidery system, the embroidery frame assembly comprising;
- an embroidery frame (50) having a first frame (51) and a second frame (53) and a device for at least one of clamping or holding a portion of a planar formation (1) to be processed between the first and second frames (51, 53), the first frame (51) is adapted to be disposed on an upper side and the second frame (53) is adapted to be disposed on a lower side of the planar formation (1),
- a secondary connector (57) which is configured to be releasably connectable to a primary connector (37) of an embroidery module (30) disposed outside the first frame (51), so as to be radially spaced apart from the first frame, and is rigidly connected in a permanent or releasable manner to the first frame (51) by a bridge (61),
- wherein the bridge (61) comprises at least one connecting portion (63) which connects the first frame (51) to the secondary connector (57) and bridges the second frame (53) when the second frame is connected to the first frame (51), such that the bridge (61) and the at least one connecting portion (63) are free from contact with the second frame (53), and wherein a spacing (L4), or a height of a void defined between the connecting portion (63) and the second frame (53) is from 1 centimeter to 10 centimeters.
