DE2151966C - Pneumatic cover press with cover turning and cover device for covering parts of upholstered furniture - Google Patents

Description

The invention relates to a pneumatic relationship. This configuration is used to cover press with cover turning and covering device parts with different widths,
For referring to parts of upholstered furniture, best- The constructive implementation of the first starting from a frame, on the lower transverse structure provides that the parallel guide strives for two support surfaces for receiving part of the transverse upholstered furniture and connected to the pressure cylinder on the upper cross strut of the strut has fixed guides on which the press cylinders are arranged with the press beam, a half-shell is attached, and two in the guide

stanchions guided handlebars to which the other half-shell is attached. One half-shell is opposite the other rigid, while the other corresponding to the wedge shape of the part to be purchased is movable.

It has been found to be useful to design the guides as hollow profiles, the handlebars in insert these hollow profiles and slide rollers resting against them on the inner walls of the hollow profiles to fix.

A stop for limiting the outward movement of the handlebars is also advantageously provided.

The design, which is used to cover parts of different widths, is structurally such that that the parallel guide attached to a cross strut connected to the printing cylinder Has leadership, in this guide two handlebars are displaceable and the two half-shells to the Handlebars are attached.

The advantage here is that the guide is a hollow profile, the links from both ends in the hollow au ς; _Ρ Hooves over a guide rod 42. mung through. You loud. uoer base plate

The entire device rests on a base plate IO and is mounted on a stand 12. From the bottom plate 10 go further columns 14, the the support surface 16 carry. A stand 18 is also fastened to the base plate 10. On his At the upper end, this carries a boom 20, on which in turn the press cylinder 22 is arranged. to the piston rod 24 belongs to the press cylinder 22. On the front side of the boom 20 there are valves Valve levers 26 arranged. The pneumatic cylinders are controlled with these valves. Through the boom 20 also pass through guide rods 28 which are used for parallel guidance. At the top Lockable stop rings 30 are located at the end of the guide rods 28. At the lower end of the piston rod 24 the press beam 32 is attached. The guide rods 28 with the press beam 32 are likewise connected. Sleeves 33 are held in a displaceable and lockable manner on the press beam 32. These pods 33 carry the hold-downs 34. These hold-downs 34 press on the furniture part 36 to be covered. This Furniture part 36 stands on the support surface 16 and is placed on it by the lower part 34.

The pressure cylinder 38, which can be acted upon by pressure medium from both sides, is arranged in the stand 18. The piston rod 40 belongs to the pressure cylinder. AJ of the piston rod 40 sits a cross member 44. This cross member 44 passes through a recess provided in the front of the stand 18.
