Abstract
An apparatus for advancing positions of a web material has a first transporter at which the pieces are separated from a web, a clamp which transfers the pieces to the plane of a second transporter and a second transporter operating in this plane in a direction orthogonal to the displacement direction of the first transporter. The second transporter has at least one conveyor at least part of which is movable toward and away from the clamp and toward which the clamp can be moved so that the pieces are transferred to the conveyor and can be displaced by the latter with no spacing between them or with only a limited spacing between them.
Claims18
An apparatus for conveying flat pieces of a web, comprising:
- a first transporter for displacing a web subdividable into a succession of flat pieces of the web along a first path in a first direction;
- a second transporter defining a second path in a plane parallel to a plane of said first path for receiving said flat pieces and displacing the received flat pieces in a second direction perpendicular to said first direction;
- and
- clamping means engageable with said flat pieces at a location along said first path for transferring said flat pieces to said second path for engagement by said second transporter,
- said second transporter comprising:
- a strip-shaped support extending in said second direction away from a location along said second path at which said flat pieces are transferred from said first path to said second path,
- a continuously driven first conveyor element having a stretch traveling in said second direction and running along said support for entraining said flat pieces along said support, and
- further means for displacing at least an up-stream part of said conveyor element toward said location along said second path for receiving a transferred flat piece on said second transporter.

An apparatus for forming and conveying flat pieces of a textile web, comprising:
- a first transporter including a tongs engageable with a leading edge of a textile web and a transport slider for displacing the textile along a first path in a first direction in one plane;
- separating means along said first path for severing flat pieces from said web whereby a succession of said flat pieces from said web are displaced along said first path in said first direction;
- a second transporter defining a second path in a second plane parallel to said one plane for receiving said flat pieces and displacing the received flat pieces in a second direction perpendicular to said first direction, said planes being spaced apart;
- and
- clamping means engageable with said flat pieces at a location along said first path for transferring said flat pieces to said second path for engagement by said second transporter, said clamping means including pairs of clamps engaging respective flat pieces inwardly of but close to opposite edges of the flat piece, said clamps being engageable with each flat piece in the plane of said first path, being shiftable with the engaged flat piece into the plane of said second path, and being shiftable toward and away from said second transporter, said second transporter being shiftable toward and away from said clamping means.

A method of forming and conveying flat pieces of a textile web, comprising the steps of:
- (a) gripping a leading edge of said textile web and drawing said textile web in a first direction along a first path in a first plane;
- (b) cutting a flat piece from said textile web on said first path in said first plane to define a trailing edge on said flat piece;
- (c) engaging said flat piece by two pairs of clamping bars in said first plane with each pair of clamping bars gripping said flat piece inwardly of a respective one of said edges and extending perpendicularly to said direction;
- (d) shifting said flat piece clamped by said pairs of clamping bars into a second plane parallel to but spaced from said first plane;
- (e) moving said clamping bars with said flat piece clamped thereby in a second direction perpendicular to said first direction to displace the flat piece along a second path in said second plane and moving at least parts of a pair of continuously driven endless conveyor elements having stretches traveling in said second direction, opposite said second direction toward said clamping bars, and engaging said edges between said stretches and elongated supports juxtaposed with said stretches;
- and
- (f) thereafter, releasing said flat piece from said clamping bars, moving at least said parts of said pair of continuously driven endless conveyor elements back to an initial position and continuing to displace said flat piece in said second plane in said second direction between said stretches and elongated supports juxtaposed with said stretches.
