A method of preparing a composite article including providing a first bias assembly with a first bias roll; providing a first non-bias assembly with a first non-bias roll; positioning the first bias assembly to a dispensing position; dispensing a bias ply from the first bias roll along a bias path on a mold; cutting the bias ply; positioning the first non-bias assembly to a dispensing position; dispensing a non-bias ply from the first non-bias roll; and cutting the non-bias ply; wherein the bias path and the non-bias path are substantially parallel.

Disclosed herein are systems and devices which transport and stack flexible textile workpieces (e.g., clothing) in a processing line. A proposed stacking device includes a conveyor belt wound through a series of rollers which permit horizontal extension of the conveyor path toward a downstream workstation. The extendable conveyor path allows for easy transferring and stacking of the workpieces at the downstream workstation.

A compactor for lengthwise compressive shrinkage of fabrics including an infeed roller and an outfeed roller that are fixed positioned parallel to one another as to define a compaction zone, a pressure roller that is movable and positioned above the compaction zone as to be self-centering between the infeed roller and the outfeed roller and as to define an infeed nip-point between the infeed roller and the pressure roller and an outfeed nip-point between the outfeed roller and the pressure roller, and a saddle assembly positioned within the compaction zone, the saddle assembly including a bed liner having an upper surface facing the pressure roller and a lower surface opposite the upper surface.

A slit device including a first transport section which transports a web in a transport direction while nipping the web, a second transport section which is disposed in parallel with a direction intersecting the transport direction of the first transport section and which transports the web in the transport direction while nipping the web, and a cutting section which is disposed between the first transport section and the second transport section in a direction intersecting the transport direction and which cuts the web along the transport direction, in which a cutting position at which the web is cut by the cutting section is a position within a nipping area where the first transport section nips the web along the transport direction, or is a position downstream of the nipping area in the transport direction.

A single material sheet is picked from a support member. A gripping member is aligned above the support member, where the gripping member includes a pair of spaced apart pinching members movably coupled with a main frame, and each pinching member includes an exposed gripping surface that is substantially planar and that faces an exposed surface of the material sheet. The gripping member is moved a first distance toward the exposed surface of the material sheet such that the gripping surfaces of the pinching members engage a portion of the material sheet. The pinching members for the gripping member are moved toward each other while the pinching members engage the portion of the material sheet so as to pinch the portion of the material sheet between the pinching members and vertically displace the material sheet from the support member.

Material moving apparatus, systems and methods are presented which can include an air material mover. Airflow through orifices can create a localized vacuum such that the uppermost or top layer of material can be separated from the stack of material. The airflow can interact with the material to produce flutter, which assists in separating lower layers from the uppermost layer. A material gripper can grip the uppermost or top layer of material for removal from the stack and repositioning in a work area.

Various examples are provided related to end effectors for use in, e.g., automation of sewing robots. In one example, among others, a compliant perimeter end effector includes a mounting bracket having a contact mounting flange, a plurality of compliant material contact elements coupled about a perimeter of the contact mounting flange. The mounting bracket can couple to a manipulator including, e.g., an industrial robot or other manipulation assembly. The compliant material contact elements can include a contact interface that can engage with a piece of material. The compliant material contact elements can precisely transfer material on a workspace with surface irregularities while equally distributing force to the material.

A method for gripping, moving and releasing a piece of cloth with a gripper that is initially placed with opposed, movable, coherent, flexible surface parts in contact with the piece of cloth, and the surface parts are moved with respect to each other and with respect to the gripper in a gripping action, in order to pinch and hold on to the piece of cloth. The gripper with the piece of cloth pinched between the surface parts is moved to a different location, wherein the surface parts move in a reverse direction in order to release the piece of cloth. While in contact with the piece of cloth, the opposed surface parts are moved along a path which brings the surface parts both closer to each other and moves them in a direction away from the piece of cloth.

A pick-up device picking up stacked sheet-shaped workpieces from the top, the device includes a nozzle mechanism that includes a pick-up nozzle pulling up a first workpiece from the top of the stacked workpieces by air blowing, and a holding mechanism that holds the first workpiece from the top. The pick-up nozzle includes a ventilation groove provided on a bottom surface opposite to an upper surface of the first workpiece from the top and passing through to an air blowing side end part of the bottom surface, and a nozzle port blowing air toward the air blowing side end part of the bottom surface along the inside of the ventilation groove, and the air blowing side end part of a groove inner bottom surface of the ventilation groove is formed in a shape directed in a direction of being separated from the workpiece.

Some embodiments include a fabric separator comprising a body, a drum, a gas intake, a sensor, and a clamp. In some embodiments, the drum has an outer surface, is coupled with the body, and has a drum rotatable about an axis. The gas intake may flow gas in a rotational direction of the drum such that a low pressure zone is created on at least a portion of the outer surface of the drum. The sensor may be coupled with the body. The clamp may be in communication with the sensor and coupled with the body. The clamp having an engaged mode where the clamp is pressed against a portion of the drum and a disengaged where the clamp is not pressed against a portion of the drum, the clamp transitions from the engaged mode to the disengaged mode based on a signal from the sensor.
